Cancer Trends in India Present a Confusing Paradox

In India, women are diagnosed with cancer more frequently, yet men experience higher mortality rates linked to the disease. This striking contradiction comes from a study analyzing the latest cancer registry data in the country.

Women represent just over half of all new cancer cases, but men account for most fatalities. India stands out internationally; in 2022, approximately 197 individuals per 100,000 were diagnosed with cancer. The figures reveal that for men, the diagnosis rate was about 212, while for women, it was lower at 186.

Globally, nearly 20 million new cancer cases were reported in 2022, with men making up around 10.3 million and women about 9.7 million. The American Cancer Society notes that, in the U.S., men and women have almost equal lifetime risks of developing cancer.

Among women in India, breast, cervical, and ovarian cancers are the most prevalent, with these two types comprising nearly 40% of cases. Cervical cancer is often linked to infections like the human papillomavirus (HPV), while breast and ovarian cancers are frequently influenced by hormonal factors. The increase in these hormone-related cancers is also associated with lifestyle changes—such as delayed pregnancies, less breastfeeding, obesity, and less active living.

Conversely, men typically face higher incidences of oral, lung, and prostate cancers, with tobacco use accounting for 40% of preventable cancer cases, particularly oral and lung cancers.

This raises questions about India’s unique situation. Is it due to earlier diagnoses for women? Are male cancers inherently more aggressive? Or perhaps lifestyle habits, like smoking, contribute to worse outcomes for men? Access, awareness, and treatment differences between genders may also play a role.

Increased awareness campaigns and enhanced medical facilities have allowed cancers frequently found in women to be detected earlier. Given the long latency periods of many cancers, treatment outcomes for women tend to be better, resulting in lower mortality rates.

Men, however, often struggle because their cancers correlate more closely with lifestyle choices—smoking and alcohol use significantly impact lung and oral cancers, which tend to be more aggressive and less responsive to treatments. Moreover, men are less likely to seek preventive medical care, contributing to their higher mortality despite lower incidence rates compared to women.

Ravi Mehrotra, a cancer specialist, pointed out that the public health focus on women’s health can be a double-edged sword. There’s greater awareness and screening for women, leading to early detection. Yet, discussions on men’s health often do not extend beyond tobacco-related cancers.

Dr. Mehrotra also noted that women are generally more engaged in reproductive health checks, giving them more opportunities to see doctors. Many men, in contrast, might never consult a physician throughout their lives.

It’s essential to recognize that India’s cancer concerns vary significantly across regions and cancer types. Data indicates that about 11% of the Indian population faces a lifetime risk of developing cancer. Projections for 2024 suggest around 1.56 million new cases and 874,000 deaths.

Interestingly, the northeastern regions of India highlight a stark cancer crisis, with Aizawl in Mizoram reporting lifetime risks double the national average. This area’s lifestyle is largely blamed for the rise in cancer cases, with tobacco use being particularly rampant.

In Assam’s Barak Valley, chewing tobacco is prevalent, whereas smoking dominates Mizoram, compounded by factors like alcohol consumption and food preparation methods that contribute to cancer risk. Dr. R Ravi Kannan believes these lifestyle factors play a crucial role rather than genetic predispositions.

This issue is not limited to the northeast. For instance, Srinagar has the highest lung cancer rates among men, whereas Hyderabad leads for breast cancer in women. Men in Delhi are diagnosed at higher rates across all cancer types compared to other regions after adjusting for age.

Oral cancer rates are also climbing, reported to be increasing among men and, in some areas, among women too.

In essence, India’s cancer landscape reflects a complex interplay of social factors and lifestyle choices. This challenge is not just a national issue but resonates globally, where disparities in cancer diagnoses and outcomes are shaped by access to healthcare and socioeconomic conditions.

As India continues to grapple with this disease, there’s a pressing need for focused prevention efforts, improved access, early detection strategies, and lifestyle modifications for better health outcomes.
