The leading cause of death, globally, for women, is breast cancer. While women are more self-aware of the disease and the causes, it is highly recommended that they go for mammography, the standard screening approach for breast cancer starting 40 years. Experts, however, suggest that the decision to undergo mammography should depend on factors such as age, personal and family history of breast cancer, breast density and any abnormalities felt during self-examination. Women in their 30s have dense breasts that can easily obscure any underlying abnormalities during screening. It is essential for women in their 30s to consult their doctors to assess any indication of breast cancer and discuss the right age for mammography, unless she has a genetic inclination of breast cancer. It is also important for every woman, starting in their 20s, to learn self-examination of breasts and report any abnormality to her doctor.
