Assessing the awareness regarding cervical cancer in Vidarbha: A Cross-Sectional Study

Introduction

Cancer is one of the most neophobic disease of the 20th century and is still spreading today and becoming more common. Every fourth individual has a lifelong risk of developing cancer because of the dire condition.¹ It’s predicted that nearly 4 thousand new cases in 2020, were recorded, and due to that cervical cancer will become the 4^th most frequent malignancy among females worldwide. It’s predicted that around 3 lakh 42 thousand cervical cancer fatalities will occur in low and middle-income countries in the year 2020.² Destruction of cancer cells are living cells that have been partially transformed into pathogenic organisms or the building blocks of tumors. Understanding cancers leads to challenging philosophical issues because they both undermine and make use of multicellular organization mechanisms.³ The predominant cell type inside the reactive stroma of several tumor forms is cancer-associated fibroblasts (CAFs). Numerous earlier investigations have demonstrated that CAFs play a pro-tumorigenic role by secreting different growth factors such as; cytokines, and chemokines as well as by degrading extracellular matrix.⁴

The emphasis has been on biological investigations and coding for cancer for a very long time and has been changing quickly. Despite the huge effort being made to comprehend the development of cancer cells are the source of the malignant tissues and the method by which they spread and relapse.⁵ Just a few of the several cellular processes in which receptor tyrosine kinases (RTKs) are active include growth, motility, differentiation, and metabolism. As a result, aberrant RTK signalling plays a role in many human diseases, most notably cancer.⁶ Cancerous processes modify protooncogenes and tumor suppressor genes, which encode proteins for signal transduction. The absence of both repressive signals for cell proliferation and the susceptibility of cells to repressive signals may be the cause of many of the damages that result in carcinogenesis. The cell has systems for both receiving apoptotic-antitumor signals and carrying out these commands.⁷

There are mostly 12 types of known cancers among all that, the most often cancers in females are – breast carcinoma, endometrial carcinoma, lung carcinoma, cervical carcinoma, colorectal carcinoma, ovarian carcinoma, skin carcinoma; whereas the most often occurred cancers in males are – colorectal carcinoma, bladder carcinoma, prostate carcinoma, lung carcinoma.⁸

Discussion

Cervical cancer develops progressively over a certain amount of time.¹⁰ Most cases take place in less developed countries where there are no reliable testing campaigns available. Some of the risk factors include acquired immunodeficiency syndrome, smoking, and human papillomavirus exposure. Treatment-related to extended morbidity is common, however, most women with initial-stage tumours can be cured. According to the outcomes of randomized clinical research, chemotherapy, and radiation therapy is considered a standard of care for cancer-developed patients and especially for women with locally advanced cancer, whereas its applicability to women in less developed nations is largely not tested.¹¹ According to circumstantial evidence, cervical cancer screening should result in a 90% depletion in the prevalence and mortality of invasive cervical cancer.¹² According to previous studies, the effectiveness is improved by less than 5% depending on the age at which the expurgating phase is started for instance age 17 or 20 years, if screening is done every 1 or 2 years rather than every 3 years there will be a decrease in the incidence rate of cancer. From roughly the age of 20 to roughly the age of 65, screening is advised at least every three years.¹²

Cervical cancer (CC) continues to be the subsequent common malignancy among females in developing countries. Therefore, it is requisite to expand people understanding regarding the molecular pathogenesis of cervical cancer, as well as to suggest new treatment targets and procedures for the early detection of this illness. The anatomical status of normal cells and the changes brought on by the emergence of tumours can be ascertained through differential expression analysis employing high-throughput techniques applied to biological materials.¹³ In the past 20 years, researchers have discovered an increasing number of head and neck squamous cell carcinoma (HNSCC) patients with tumours that are human papillomavirus (HPV) positive and develop in younger people¹⁴ The human papillomavirus causes more than 95% of the manifestation of cervical cancer (HPV).¹⁵ Contamination with (human papillomavirus) HPV is required for the evolution of cervical cancer and its precursors. HPV also causes cancers of the respiratory and gastrointestinal tracts, as well as precancerous lesions and cancers elsewhere in the female and male lower reproductive tract.² The HPV infection is also associated with the lung cancer, however there is no convincing evidence of the claim.¹⁶ Infection usually occurs through intercourse with the virus that deposits in the basal lamina of the cervical epithelium. It is then taken up by basal cells and viral enhancement occurs in the outer layer of epithelium i.e. squamous epithelium matures. It avoids the host’s immune system during this phase and frequently does not elicit a reaction from the immune system. Clinically detectable serum antibody levels are not present in about 50% of HPV-positive women. Therefore, there is a risk of reinfection with the same type of HPV.² The changes in the genes include dilation of oncogenes and variant of tumour suppressor gene.¹⁷ HIF-1α i.e. hypoxia- inducible factor-1α enacts in enhancing a tumour ontogenesis, which is attested by its upregulation in many of the human cancers such as breast, cervix, lung and oral cavity.¹⁸ Exosomes, which contain a variety of chemicals, are the source of hypoxic tumour cells that alter the immune system and encourage the growth of cancer.¹⁹
