Breast cancer Estadimento

>Breast cancer is the second leading cause of death of women due to cancer. Occurs when the breast cells divide and reproduce very quickly and chaotic. The causes of breast cancer may be associated with the interaction of genetic factors with lifestyles, environment and reproductive habits. There are certain risk factors that increase the possibility of a woman having a breast cancer, such as heredity.

When it is done an exam in which breast cancer is detected, this survey also highlights the extent or stage of cancer, i.e. it is possible to know the size of the cancer, and whether it has spread from its original location. Done the diagnosis, doctors will decide what treatment is best suited.

Generally speaking, there are four stages of evolution of breast cancer from stage 1, in which the tumor is still small and localized, even at stage 4, in which the tumor has already spread to other parts of the body. When the tumor spreads to distant parts of the body, it is said that this is a secondary or metastatic cancer.

Based on the classification of malignant tumours, TMN (Tumor-node-Metastasis). This classification was proposed by the International Union against cancer, according to the characteristics of the primary tumor, lymph nodes, lymphatic drainage chains of the body in which the tumor is located and the presence or absence of distant metastases.
