Or it might be given to shrink a more extensive breast cancer before surgery (this may mean breast-conserving surgery is an option, rather than a mastectomy).?People with certain types of breast cancer, such as triple negative or inflammatory breast cancer, or whose breast cancer is HER2 positive, may be more likely to have chemotherapy before surgery.
Chemotherapy is given before surgery is called primary or neo-adjuvant chemotherapy.?
Secondary breast cancer:
Chemotherapy can be given to people with secondary breast cancer when breast cancer cells have spread to another part of the body.
Chemotherapy can shrink or slow the growth of secondary breast cancer. It can also help reduce some symptoms.
