In a landmark analysis of cancer cases in Delhi, Mumbai, Chennai, and Bangalore, the Indian Medical Research Council (ICMR) reported that the incidence of cervical cancer was low in some cases, up to 50%, and in some cases about 50%. And, trends in ICMR’s unreleased report, ‘Time Trends in Cancer Incidence Rates (1982-2005)’, are universal in all four cities.
In the case of cervical cancer, the cases were as follows: In 1982, 32.4 new cases of cervical cancer were reported per 100,000 population per year in Bangalore. The number has dropped to 27.2 in 1991, 17 in 2001 and 18.2 in 2005.
Delhi records have been available since 1988, with 25.9 new cervical cancer cases per 100,000 population in the same year. It then dropped to 19.1 in 1998 and then to 18.9 in 2005.
Mumbai, which recorded 17.9 new cervical cancer cases per 100,000 population in 1982, recorded 12.7 new cases in 2005.
In the span of 24 years, Chennai has seen a 50% drop in cervical cancer cases. In 1982, Chennai recorded 41 cases per 100,000 population; Nearly a decade later, in 1991, the number of new cases in Chennai dropped to 33.4. In 2005, new cases dropped to 22 per 100,000 population.
Cervical cancer caused by human papillomavirus (HPV) is often referred to as a poor woman’s disease. It was previously believed that cervical cancer is common in India, with more than 1.3 lakh new cases being reported each year, and 74,000 women die from the disease annually.
The number of breast cancer cases in Bangalore has doubled since 1982 – 15.8 per lakh population in 1982, to 32.2 in 2005 – in Chennai with 33.5 new breast cancer cases in 2005.
Delhi recorded 24.8 new cases of breast cancer per 100,000 women a year, up from 32.2 in 2005. In 1982, Mumbai recorded 20.8 new breast cancer cases per 100,000 population, an increase of about 10% in 2005.
ICMR Director and Health Research Division Secretary Dr VM Katoch told TOI, “ The decline in cancer cervical cases is present in all cancer registries. Factors such as late marriage and fewer children can lead to decline. ”
Dr Vinod Raina, head of medical oncology at AIMS and head of the Delhi Cancer Registry, told TOI, “A growing number of women are now distributing in institutions, which has greatly improved their personal hygiene. Women are now getting married late and giving birth to fewer children, all of which have led to cases of cervical cancer. ”
Ironically, these are the same factors, according to Dr Raina, who has increased breast cancer rates in India.
“ Western lifestyle, increased consumption of fat products, obesity, delayed marriages, delayed childbearing and fewer pregnancies lead to less breastfeeding and fewer contraceptives, all of which are believed to be at increased risk for breast cancer. This cancer is also inevitable with an aging population, ” he said.
However, Dr Raina is quick to point out that the rate of breast cancer in India is much lower than in Western countries, which records about 100 new cases per 100,000 population.
Dr. According to Katoch, the report depicts changes in rates of cancer incidence and is the first of any chronic disease in India.
Some anatomical sites of cancer have shown a remarkably consistent increase in all registrations, with breast cancer being one of them. “These data will now help us enhance India’s healthcare system and tell us how we can improve the diagnostic capabilities and expertise of some of the most affected Indians,” Dr Katoch said.
