Breast cancer on the rise in younger women
NEW DELHI: A study has found that the incidence of advanced breast cancer among American women between 25-39 has steadily increased since the mid-1970s. The findings, published in the Journal of American Medical Association, are devastating because breast cancer patients under 40 years are more likely to have an aggressive form of the disease and face lower survival rates. However, doctors here say developing countries like India have more to worry in comparison.
Additional professor in the department of surgical oncology, AIIMS, Dr S V S Deo says, "Breast cancer cases in India have increased by 10-15% in the last decade. These numbers are likely to rise further - 60-70% of the cases would be in developing countries like India in the future." The number of younger patients in the US has increased at just 2% a year in the last three decades, comprising 1.8% of the total breast cancer cases. In comparison, different studies peg the number of young patients in India between 10-16%.
In recent years, breast cancer has emerged as the most common form of cancer among urban Indian women. Dr Geeta K, senior consultant in surgical oncology at Max Cancer Centre, Delhi, adds, "Of the 25-30 new breast cancer cases that we get in a month, five-six are in the under-35 age group. Some are in their 20s."
Just 10% of these cases are said to be of genetic causes - lifestyle is said to be the major culprit in the rest. Dr Anil Dhar, director, medical oncology, Fortis Memorial Research Institute, Gurgaon, says, "There is no data but personally I feel that exposure to chemicals (in food and the environment) is an important factor in causing breast cancer."
