Sign of Breast cancer
- Lump or Thickening: A lump or thickening in the breast or underarm is a common sign. Not all lumps are cancerous, but any new lump should be evaluated.
- Changes in Breast Size or Shape: Changes in the size or shape of one breast can be a sign. This includes asymmetry between the two breasts.
- Changes in Skin Texture: Redness, puckering, dimpling, or other changes in the skin on or around the breast can be a cause for concern.
- Nipple Changes: Changes in the nipple, such as inversion, flattening, or discharge (other than breast milk), should be investigated.
- Breast Pain or Discomfort: While breast pain is usually not a symptom of breast cancer, persistent or unexplained pain should be evaluated.
- Swelling: Swelling of part or all of the breast, even without a distinct lump, can be a sign.
- Unexplained Weight Loss: Sudden and unexplained weight loss without changes in diet or exercise can be a symptom of various health issues, including some types of breast cancer.
- Changes in the Appearance of the Nipple or Areola: This can include scaling, itching, or a rash.
- Unexplained Fatigue: While fatigue is a general symptom, unexplained persistent fatigue, especially if accompanied by other symptoms, should be addressed.
- Axillary (Underarm) Lymph Node Changes: Swelling or tenderness in the lymph nodes under the arm could be a sign that breast cancer has spread.
It’s important to note that these symptoms can also be caused by conditions other than breast cancer. Regular breast self-exams, clinical breast exams by a healthcare professional, and mammograms as recommended by your doctor are essential for early detection and prevention. If you notice any changes or have concerns, seek prompt medical attention.
Treatment of Breast Cancer
Here are some common treatments for breast cancer:
- Surgery:
- Lumpectomy: Removal of the tumor and a small margin of surrounding normal tissue. This is often an option for early-stage breast cancer.
- Mastectomy: Removal of the entire breast. This may be necessary if the cancer is large or if there are multiple tumors.
- Sentinel Lymph Node Biopsy: Removal and examination of the lymph nodes to determine if the cancer has spread.
- Radiation Therapy:
- External Beam Radiation: High-energy beams are targeted at the affected breast or lymph nodes to destroy cancer cells or prevent their growth.
- Internal Radiation (Brachytherapy): Radioactive material is placed directly into or near the tumor site.
- Chemotherapy:
- Systemic Medications: Drugs are administered orally or intravenously to kill cancer cells or stop their growth. Chemotherapy is often used in addition to surgery and/or radiation.
- Neoadjuvant Chemotherapy: Given before surgery to shrink tumors.
- Adjuvant Chemotherapy: Given after surgery to eliminate any remaining cancer cells.
- Hormone Therapy:
- Selective Estrogen Receptor Modulators (SERMs): Drugs such as tamoxifen block the effects of estrogen on breast cancer cells.
- Aromatase Inhibitors: These drugs, like anastrozole and letrozole, reduce the production of estrogen in postmenopausal women.
- Ovarian Ablation: Surgical or medical methods to stop the ovaries from producing estrogen, usually in premenopausal women.
- Targeted Therapy:
- Herceptin (Trastuzumab): Used for HER2-positive breast cancers to target the HER2 protein.
- Tyrosine Kinase Inhibitors: Drugs like lapatinib and neratinib target specific proteins involved in cancer growth.
- Immunotherapy:
- Checkpoint Inhibitors: Drugs like pembrolizumab and atezolizumab help the immune system recognize and attack cancer cells.
- Bone-Directed Therapy:
- Bisphosphonates and Denosumab: Used to strengthen bones and reduce the risk of fractures, especially in cancers that have spread to the bones.
- Clinical Trials:
- Participation in clinical trials may offer access to new treatments or combinations of existing treatments.
