Invasive Breast Cancer
Invasive breast cancer is a type of breast cancer where the malignant (cancerous) cells have grown beyond the milk ducts or lobules and have invaded the surrounding breast tissue. This is in contrast to in situ (non-invasive) carcinoma, where the cancer cells have not spread beyond the ducts or lobules.
Here are some key points about invasive breast cancer:
-
Types: There are several types of invasive breast cancer, including invasive ductal carcinoma (IDC), invasive lobular carcinoma (ILC), and others.
-
Spread: Invasive breast cancer can spread to other parts of the body through the lymphatic system or bloodstream, a process known as metastasis.
-
Symptoms: Common symptoms include a new lump or thickening in the breast, changes in breast size or shape, nipple changes, or skin changes such as dimpling or an orange-peel texture.
-
Staging: The cancer is staged from I to IV, with stage IV indicating that the cancer has spread to other organs in the body.
-
Diagnosis: A diagnosis is made through a combination of physical examination, imaging tests (mammograms, ultrasounds, MRI), and a biopsy.
-
Treatment: Treatment options can include surgery, radiation therapy, chemotherapy, hormone therapy, targeted therapy, and immunotherapy, depending on the type and stage of the cancer.
-
Prognosis: The prognosis for invasive breast cancer depends on various factors, including the stage of the cancer, the type of cancer, the patient's overall health, and the effectiveness of the treatment.
-
Survival Rates: With advancements in treatment and early detection, survival rates for invasive breast cancer have improved significantly.
Invasive breast cancer, early detection and diagnosis are crucial for better outcomes. Regular screenings and awareness of the symptoms can aid in early identification and treatment.
