1 Introduction

Childhood cancer is the leading cause of death in children,especially in low and middle-income countries.Their likelihood of survival heavily rests on the country where they live.The chance of curing childhood cancer in high-income countries is above eighty percent, whereas in low and in middleincome countries,it is a mere forty-five percent.This difference in curing rate owes to many factors,such as late diagnosing and cancer diagnosed at its late stages due to unavailability of resources,cost of treatment(the treatment cost is rather high in later stages),or incorrect diagnostics and inappropriate treatment.The survival rate can be increased if low and in middle-income countries improve the access to necessary medicines and technologies.Generally speaking,the most productive way to reduce the effects of childhood cancer is by effective and evidence-based therapy with appropriate nurturing care.

The chances of curing childhood cancer, and the cost of treatment with lesser suffering, can be improved if it is identified early, and appropriate treatment is provided immediately.A correct diagnosis is required to treat childhood cancer efficiently with the right treatment,which may include surgeries, radiotherapy, and chemotherapy.For early diagnosing, we should consider the following three aspects:

1) Parents should know about childhood cancer so that they can perceive its symptoms and consult a medical expert.

2) The medical expert should be skilled enough and investigate the case promptly in order to cater for the right treatment.

3) The patient has accessibility to the right treatment at right time.

When someone is diagnosed with cancer, the chances of recovery and survival increase if it is detected in an early stage, even with the least amount of financial and physical suffering.The lowand middle-income countries should run education campaigns for parents with the help of competent doctors so that in the presence of symptoms in any child,their parents can respond without delay.This task requires the joint effort of civil society and non-governmental organizations.In 2018,the World Health Organization launched a global initiative on cancer in children.As part of this initiative,they provided governments with professional guidance and support to maintain high-quality childhood cancer programs.They aim to increase childhood cancer survival rates,and by 2030 that rate should be at least sixty percent.

Medical information is very sensitive and contains many uncertainties.Every expert may have their personal opinion on a health record,and it may become rather difficult to make an accurate diagnostic based on these reports.In such uncertain situations,fuzzy logic can play an important role in making decisions among different alternative diagnostics.Many extensions of fuzzy sets theory have been proposed[1,2].In fact research has provided many medical applications that have taken advantage of different fuzzy approaches[3,4],and of models of vague knowledge born from alternative narratives[5].Feng et al.[6,7]generalized intuitionistic fuzzy soft sets and related multi attribute decision making methods.By inspiration of these applied studies,we have selected a powerful and flexible model for the representation of undertain knowledge.It has been popularized by Yager et al.[8,9],who coined the term Pythagorean fuzzy sets(PFSs).PFSs improve the performance of intuitionistic fuzzy sets,which for each alternative,provide a fuzzy assessment of both membership(μ)and nonmembership(ν)in such a way thatμ+ν≤1.In PFSs however,assessments that meet the relaxed conditionμ2+ν2≤1 are acceptable.The PFS model has become one of the most influential notions in fuzzy modeling,since it allows us to accept more uncertain appraisals than the intuitionistic fuzzy or fuzzy sets,and consequently,its applications are potentially wider.The next summary of recent results testifies to this claim.

Yucesan et al.[10] presented the ideas of Pythagorean fuzzy analytic hierarchy method and Pythagorean fuzzy method for order decision by comparison to the ideal solution,in order to present an exact decision-making technique for estimating hospital service quality.Guleria et al.[11]proposed a new (R,S)-norm discriminant measure of Pythagorean fuzzy sets and proved some interesting features.Their monotonicity with respect to the parameters R&S were studied too.This information measure is utilized in some problems related to medical diagnosis or pattern recognition.Extensions and hybrid models based on PFSs have been put forward too.Rahman [12] extended the spirit of some popular aggregation operators to the more general framework of interval-valued Pythagorean fuzzy numbers, thus producing the so-called GIVPFWA, GIVPFOWA, and GIVPFHA operators.They discussed their properties, and argued that their generalized operators are more reliable and accurate than the existing aggregation operators.Zulqarnain et al.[13] proposed the averaging and geometric operators of Pythagorean fuzzy hypersoft sets.They also introduced a novel TOPSIS method in this new environment.They applied this methodology to a case-study of selection of multipurpose masks for protection against COVID-19.Yue et al.[14]proposed novel score function of hesitant fuzzy numbers and prove the validity of this function using an example.Yue[15]proposed a novel bilateral matching (BM) decision-making method for knowledge innovation management considering the matching willingness of bilateral enterprises.Ejegwa[16]improved composite relation for Pythagorean fuzzy sets and applied it to medical diagnosis.Many other decision-making methods have been suggested in the literature[17-25].

The following targets motivate the research contained in this article:

1) Early diagnosis of cancer in children can reduce overall mortality and expense of treatment,which ultimately reduces the patient’s suffering.

2) Effective handling of vague and uncertain data in a medical context is required.

3) Get opinions of available medical experts and decide the final treatment.

4) Contribution towards WHO’s goal of increasing survival from childhood cancer by least sixty percent before 2030.

Concerning these issues,our contribution to this study is described below:

1) We develop a novel decision-making system to determine childhood cancer risk at its early stages,thus increasing the survival rate.

2) We use the Pythagorean fuzzy sets(PFS)for decision-making because it is very close to human thinking.It is characteristic of simultaneously focusing on the degree of truth, the degree of non-membership, and the degree of indeterminacy of each alternative to make it more powerful.

3) We design algorithms to demonstrate the entire performance of the model.In addition, we determine their respective time complexities.

The rest of this paper is structured as follows.Section 2 discusses preliminary work.Section 3 describes the main contributions of the paper.Then Section 4 performs a comparative analysis.Section 5 concludes the proposed work and lays out some future directions for research.

2 Preliminaries

This section summarizes some of the introductory concepts that need to be followed to completely benefit from this study.First we overview technical concepts that will help us formulate our theoretical model.Then we summarize some facts about its prospective application (namely, identification of childhood cancer).

2.1 Pythagorean Fuzzy Set[8]

LetZbe a universal set.Then,a Pythagorean fuzzy setSoverZis a set of ordered triples indexed byZ, which adopts the following form:S= {＜z,μS(z),νS(z) ＞|z∈Z}, where the functionsμS(z):Z-→[0,1]andνS(z):Z-→[0,1]respectively define the degree of membership and the degree of non-membership ofz∈ZtoS, and the inequalities 0 ≤(μS(z))2+(νS(z))2≤1 hold for eachz∈Z.The figuredefines the degree of indeterminacy ofz∈ZtoS.ObserveπS(z) ∈[0,1],andπS(z) = 0 whenever(μS(z))2+(νS(z))2= 1.We represent the set of all PFSs overZby PFS(Z).

2.2 Pythagorean Fuzzy Relation[16]

LetUandVbe two nonempty sets.A Pythagorean fuzzy relation (PFR),L, fromUtoVis a PFS overU×V.It is characterized by a membership function,μR,and a nonmembership function,νLthat meet the corresponding bounds.A PF relation or PFR fromUtoVis denoted byL(U→V).

2.3 Pythagorean Fuzzy-Technique for Order of Preference by Similarity to Ideal Solution(PF-TOP SIS)Method [20]

The PF-TOPSIS method uses linguistic terms and Pythagorean fuzzy numbers(PFNs)to represent the relative importance of experts and criteria.These linguistic terms and PFNs are predefined and used to rate any expert or criteria.The following equation is used to calculate the weight in crisp form for any Pythagorean fuzzy evaluation.Assume thatPn= [μn,νn,πn] is a Pythagorean Fuzzy Number(PFN),then its weight can be calculated by using the following formula:

Notice that the sum of all weights should be equal to 1.

LetB1andB2be the sets of benefit-type and cost-type criteria,respectively.

The Pythagorean Fuzzy Positive Ideal Solution (PFPIS)S+and Pythagorean Fuzzy Negative Ideal Solution(PFNIS)S-can be obtained as:S+={〈Rj,μS+P,νS+P〉|Rj∈C,j=1,2,....,m},

S-={〈Rj,μS-P,νS-P〉|Rj∈C,j=1,2,....,m},where

The following formula is used to calculate the distance of each alternative from PFPIS and PFNIS:

The relative closeness value of each choiceSiis calculated as follows:

The maximum relative closeness value is the best choice among all possible choices.

2.4 Pythagorean Fuzzy-Entropy(PF-Entropy)Method [21]

According to[21],the following equation computes the entropyT(P)of any criteria represented by a Pythagorean Fuzzy Number(PFN)P:

where,T*(pi)=1-|μp(zi)-νp(zi)|.

The score functionK(P)of suchPcan be defined as follows:

The weighted entropy of each criteria is calculated using the next equation:

2.5 Pythagorean Fuzzy Power Weighted Average(PFPWA)[21,22]

The support of two PFNs is calculated using the next formula:

The distance between two PFNs can be calculated using the following normalized Hamming distance:

The formula for the weighted support is as follows:

and we compute the weightsγijassociated with the PFNPijas

wherei=1,2,...,m,j=1,2,...,n,γij≥0,and

The Pythagorean Fuzzy Power Weighted Geometric(PFPWG)operator is as follows:

LetP=(μ,ν)be a PFN.Then a score functionSofP,a PFN,can be defined by the expression:

2.7 Types of Childhood Cancers

Children and teenagers tend to get different types of childhood cancers.The most common childhood cancers are discussed below:

Leukemia(D1):It is bone marrow and blood cancer.Twenty-eight percent of childhood cancer cases fall into this category.

Brain and spinal cord tumors(D2):The second most common cancer in children is the brain and spinal cord cancer.In this type of cancer,abnormal growth in tissues of the brain and spinal cord is seen causing headache,nausea,vomiting,blurred vision,and difficulty in walking and holding objects.About 26 children develop this type of cancer every year.

Neuroblastoma(D3):Neuroblastoma begins in the early forms of nerve cells seen in a developing egg or fetus.About 6 percent of cancers in adolescents are neuroblastomas.This type of cancer occurs in newborns and adolescents.It is uncommon in children over 10 years of age.Neuroblastomas mostly occur in and around the adrenal glands.However,neuroblastomas can develop in other areas of the stomach and ribs,neck,and near the spine where there are clusters of nerve cells.

Wilms Tumor (D4):Wilms’tumor begins in one or, rarely, both kidneys.It is usually found in children around 3 to 4 years of age and is rare in more mature children and adults.Wilms’tumor accounts for around 5 percent of childhood cancers.Its symptoms are fever,pain,nausea,or loss of appetite.

Lymphomas(D5):It is a disease that attacks infection-fighting cells in the immune system.These cells are called lymphocytes.These cells are found in the lymph nodes, spleen, thymus gland, bone marrow, and other parts of the body.In this disease, abnormal growth of lymphocytes has been observed.Symptoms include weight loss,fever,sweats,fatigue,and lumps under the skin in the neck,armpits,or groin area.

Retinoblastoma(D6):This type of cancer is related to the eyes.It is a rare type of cancer in which a child could not distinguish the colors of light,also had impaired vision and sensitive eyes.The pupil of the eyes becomes large.

Rhabdomyosarcoma (D7):It is an intrusive and very dangerous cancer that originates from skeletal muscle cells.It is widely believed to be a childhood disease as the vast majority of cases found are under the age of 18.It is about 3 percent of childhood cancers.

Bone Cancer(D8):This type of cancer usually occurs in older children.This type of cancer causes severe bone pain all the time.The bones become weak and can also be broken.In some cases,weight loss is also observed.

3 Pythagorean Fuzzy Model of Childhood Cancer

To make the proposed Pythagorean model more understandable, consider the block diagram shown in Fig.1.The proposed model uses nineteen symptoms as inputs.For each input,a linguistic variable is defined in the Pythagorean fuzzy number.There may benexperts,but we’re only picking three experts here.Their expertise is represented by PFNs.Symptom PFNs and expert weights are input to PF-TOPSIS,PF-entropy,and PFPWG blocks.In these blocks,the algorithm of each approach is executing and generating its final outputs.We compare the results of each method and highlight the signal output.The results of these three methods should be the same.

3.1 Algorithm for Risk Assessment of Childhood Cancer

In this subsection, we write all of the instructions that must be followed to obtain final results for any input.Each algorithm takes certain inputs and produces certain outputs.There are seven subalgorithms of the PF-TOPSIS algorithm,namely,Algorithm A,Algorithm B,Algorithm C,Algorithm D,Algorithm E,Algorithm F,and Algorithm G.Each sub-algorithm shows each step of the TOPSIS process.We also write the net time complexity of every algorithm.

Step 7:DiseaseD1is pinpointed again.

We confirm that each approach highlights the same disease based on the patient record provided.

4 Comparative Analysis

In this section, we compare the results of the Pythagorean Fuzzy TOPSIS (PF-TOPSIS), the Pythagorean Fuzzy Entropy(PF-Entropy),and the PFPWG method.To do this,we took ten different data sets and applied PF-TOPSIS, PF-Entropy, and the PFPWG techniques.The results obtained from each technique are represented by drawing bar graphs.In Fig.2,the results of PF-TOPSIS are displayed.The eight diseases are shown in different eight colors.The length of each bar shows its value obtained from the PF-TOPSIS method.In Fig.3,the results of the PF entropy are displayed.In this figure,eight diseases are also represented by different colors,and the length of the bar shows the value of each disease for each data set obtained from PF entropy method.Fig.4 shows the results of the PFPWG method.

5 Conclusion and Future Work

According to the World Health Organization (WHO), around 400,000 children are diagnosed with cancer each year and the rate of cure in low and middle-income countries is only 45 percent,which is highly unsatisfactory.To improve this percentage,WHO has launched a global initiative and provided appropriate professional guidance and resources.Their goal is to increase the survival rate up to sixty percent by the end of 2030.To help achieve this goal,we have proposed a novel model that allows doctors to diagnose the type of childhood cancer early, so that appropriate treatment can be given at the right time.This ultimately reduces the physical and financial suffering of the patient and their parents.Our model takes nineteen symptoms as inputs and determines the type of cancer.We have used Pythagorean fuzzy decision-making techniques for diagnostic purposes.We designed three algorithms, namely, Pythagorean fuzzy TOPSIS method, Pythagorean fuzzy entropy, and PFPWG.We have determined their respective time complexities.To test them,we have taken ten data sets and compared the results of the different approaches.Also,we have set forth a numerical example to make each of their steps understandable.

There are many other applications where decision-making takes place and our approaches can provide assistance.Our system is applicable when data is fuzzy and decisions must be made.So,some future directions of our work are discussed below:

Industrial automation and Industry 4.0:In Industry 4.0, we connect the devices through the internet to make a network of different things.Then through the proposed approach, the different manufacturing parts of the machines can be controlled without human intervention.We can use our proposed model in Industry 4.0 to make intelligent decisions by taking into account all parameters and making the manufacturing process more productively and efficiently.

Precision agriculture:We need various decision-making systems to automate traditional farming to increase the yields and reduce the potential risks.With our model,precision farming can be made more efficient and productive.We can make timely decisions, and automate the decision process.Through this approach,an irrigation system can be improved,and water wastage could be reduced.Our proposed approach can be useful for designing a pest control system that helps the farmer to save crops from pests timely.This approach can also be useful to monitor soil pH and other ingredients,which require for the proper growth of the crops.Through this procedure,farmers can decide the right amount of fertilizers for the field.

Computer aided diagnosis:These systems help doctors to analyze the medical images and highlight diseases based on symptoms.The proposed approach can help doctors to early detect the chances of any disease,which could happen in the future due to the patient’s routine or changes in his body and enable the doctor to prevent it from spreading more by proper medication or therapies.

Classroom monitoring:The proposed approach could be beneficial for monitoring students’activities in a large classroom and concluding which student is not attentive in class or how much students in the class are attentive.
