October is the month of breast cancer awareness across the world.
According to the World Health Organization (WHO) there are 1.38 million new cases of breast cancer a year and about 458,000 deaths worldwide.
Breast cancer is the most common cancer in women.
Doctors recommend early detection by regular self-examination and medical physical exams.
Mammography is available in developed countries for long term screening programs, but they could be costly in developing countries.
Since there is not enough understanding about the origin of breast cancer, early detection is paramount for any chances of cure. Virtually all cases of breast cancer are diagnosed by biopsy of a nodule diagnosed by palpation or mammography.
There seems to be a genetic factor as about 10% of breast cancer is related to mutations. Several genes have been implicated in familial cases.
