Cancer is a disease of the cell. Un Breast cancer is a malignant tumour which develops in the breast. One out of eleven women will develop breast cancer during their lives. The person's life - the life of the family, couples and working life - is profoundly changed.
The are various types of breast cancer
Cells from malignant tumours tend to leave their original tissue and invade neighbouring tissue. This is referred to as infiltrating cancer. Some tumours remain in their original tissue without infiltrating neighbouring tissues. The term in situ cancer ("remaining in place") is then used. Cells from infiltrating cancers can separate from the original tumour and spread through blood or lymph vessels. They then accumulate in neighbouring lymph nodes. This case is referred to as lymph node invasion.
Cancer cells tend to migrate into other organs or parts of the body where they develop new tumours called metastases. This case the cancer is referred to as being metastatic.
The various behaviours of cells depend on the type of breast cancer. © INCA
