Breast cancer is a type of cancer where cells in the breast grow uncontrollably. There are multiple types of breast cancer that are dependent on which types of cells in the breast turn cancerous. The most common types of breast cancer include invasive ductal carcinoma, where cancer cells grow outside the breast ducts into other parts of the breast tissue, and invasive lobular carcinoma, which involves cancer cells spreading from the breast lobules to the breast tissues close by.
Breast cancer can be treated using treatments such as surgery, chemotherapy, hormonal therapy, biological therapy or radiation therapy. Breast cancer clinical trials are also an option that use new treatments, procedures and devices to study if they are safe and effective, and it gives breast patients first access to options that may not yet be available to others in standard care.
Choosing the right treatment is dependent on many factors such as your specific type, stage and previous cancer treatment. It is always best to talk to your doctor about treatment options for your specific case.
