Breast Cancer

"Breast Cancer (BC) is a malignant tumor that originates from healthy mammary gland cells. The most common type of BC is a carcinoma coming from the glandular tissues. BC is most frequent among women aged between 50 and 70. It affects one in eight women on average and is the most common type of cancer among women. About one million new cases of BC are diagnosed each year worldwide, representing about a third of new cases of all female cancers in industrialized countries and 15% of new cases in developing countries. With the improvement of treatments, the survival rate of women diagnosed with BC has increased by 2% a year during the last twenty years . However, despite this improvement, the mortality due to BC remains significant among women with about 20 women over 100000 dying from this disease each year worldwide. The mortality rate of BC depends on its stage. While BC of stages I (localized tumors of less than 2 cm) and II (tumors of 2 to 5 cm without nodes) can be cured relatively simply using surgery resulting in a mortality rate of less than 50%, those of grades III (infiltrating tumors without metastases) and IV (presence of metastases) are much harder to treat, usually require heavy treatments often involving a combination of surgery, chemotherapy and radiotherapy, and result in a mortality rate of more than 50% . There are essentially three different ways to decrease the mortality rate of BC. Firstly, BC arises because of several risks factors, such as aging, disease (hyperplasia), a diet with a high intake of saturated fat, overweight, excessive alcohol consumption, exposure to ionizing radiation, the consumption of oral contraceptives, hormone replacement therapy .(Alphandéry E (2013) Efficacy of Thermotherapy to Treat Breast Cancer: A Review.
