Breast cancer remains one of the most common cancers among women in the United States. Early detection and advancements in treatment have significantly improved survival rates. This article will cover the essential aspects of breast cancer, including symptoms, various treatment options, and the latest advancements in care.
What is Breast Cancer?
Breast cancer occurs when cells in the breast grow uncontrollably, forming a tumor. It can spread to other parts of the body if not detected and treated early. There are several types of breast cancer, with invasive ductal carcinoma being the most common.
Breast Cancer Symptoms
Recognizing the early signs of breast cancer can lead to timely diagnosis and treatment. Common symptoms include:
-
A lump in the breast or underarm
-
Change in breast size or shape
-
Dimpling or puckering of the skin
-
Nipple discharge
-
Pain in the breast or nipple area
-
Redness or scaling of the nipple or breast skin
If you experience any of these symptoms, it's crucial to consult a healthcare provider for evaluation.
Breast Cancer Treatments
Surgery
Surgery is often the first treatment for breast cancer, aiming to remove the tumor and surrounding tissue. Types of surgery include:
-
Lumpectomy: Removing the tumor and a small margin of surrounding tissue.
-
Mastectomy: Removing one or both breasts, partially or entirely.
-
Reconstructive Surgery: Rebuilding the breast shape after mastectomy.
Radiation Therapy
Radiation therapy uses high-energy rays to target and kill cancer cells. It is often used after surgery to eliminate any remaining cancer cells and reduce the risk of recurrence.
Chemotherapy
Chemotherapy involves the use of drugs to destroy cancer cells. It can be administered before surgery to shrink the tumor or after surgery to kill any remaining cancer cells.
Hormone Therapy
Hormone therapy is used for cancers that are hormone receptor-positive, such as estrogen-positive breast cancer. It works by blocking the body's ability to produce hormones or by interfering with the effects of hormones on breast cancer cells.
Targeted Therapy
Targeted therapy focuses on specific molecules involved in cancer growth and progression. Drugs used in targeted therapy can block the growth and spread of cancer cells while minimizing damage to normal cells.
New Treatments for ER Positive Breast Cancer
CDK4/6 Inhibitors
CDK4/6 inhibitors are a class of drugs that have shown promising results in treating estrogen receptor-positive (ER+) breast cancer. These drugs work by inhibiting proteins that promote cancer cell growth.
PI3K Inhibitors
PI3K inhibitors target a specific enzyme involved in cell growth and survival. These drugs are used in combination with hormone therapy to treat advanced ER+ breast cancer.
Immunotherapy
Immunotherapy is an emerging treatment that harnesses the body's immune system to fight cancer. It is being studied in clinical trials for its potential to treat various types of breast cancer, including ER+ breast cancer.
Early Breast Cancer Drugs
Tamoxifen
Tamoxifen is a well-established drug used to treat early-stage hormone receptor-positive breast cancer. It works by blocking estrogen receptors on breast cancer cells.
Aromatase Inhibitors
Aromatase inhibitors, such as anastrozole, letrozole, and exemestane, reduce the amount of estrogen in the body. They are commonly used in postmenopausal women to treat early-stage hormone receptor-positive breast cancer.
HER2-Targeted Therapies
HER2-targeted therapies, such as trastuzumab and pertuzumab, are used to treat early-stage HER2-positive breast cancer. These drugs target the HER2 protein, which promotes cancer cell growth.
