Understanding breast neoplasms

Breast cancer is a disease in which cells in the breast grow out of control. According to the American Cancer Society, it usually begins in the milk ducts (ductal cancers) or the milk-producing lobules (lobular cancers). The American Cancer Society also explains that breast cancer can be non-invasive (in situ), meaning it has not grown into deeper breast tissue, or invasive, meaning it has spread into surrounding tissue. MedlinePlus notes that possible signs include a new lump or thickening in or near the breast or armpit, a change in breast size or shape, skin dimpling or puckering, a nipple turned inward, nipple discharge other than breast milk, or scaly, red, or swollen skin around the nipple or breast. Breast cancer may also be found before symptoms appear; the National Cancer Institute states that mammograms can detect breast cancer early, possibly before it has spread. MedlinePlus describes that a breast biopsy is used to diagnose breast cancer, and that doctors test the tumor for hormone (estrogen and progesterone) receptors and HER2 status to help guide care. This is general information, not medical advice.

First-line treatment

There is no single first-line treatment for breast cancer. MedlinePlus explains that treatment is based on many factors, including the type of breast cancer, its stage, whether the cancer is sensitive to hormones (mainly estrogen and progesterone), and whether it overexpresses the HER2 protein. The National Cancer Institute notes that stage is an important factor in determining which treatment may work best. Treatment categories include local treatments directed at the breast and nearby tissue — surgery and radiation therapy — and systemic treatments that can reach cancer cells throughout the body, including chemotherapy, hormone therapy, targeted therapy, and immunotherapy. More than one type may be used together. The National Cancer Institute emphasizes that you and your cancer care team work together to decide your treatment plan, so the specific approach is individualized by an oncology team for each patient. This is general information, not medical advice.
