Types and Warning Signs of Breast Cancer
Breast cancer affects the milk ducts or lobules and is categorized into different types, including invasive, inflammatory, recurrent, and metastatic. HER2-positive breast cancer results from a genetic mutation that accelerates cell growth. Since symptoms can be subtle, regular screenings and awareness of warning signs like lumps, nipple changes, and skin abnormalities are crucial. Early detection improves the chances of successful treatment.
Breast cancer develops when cells in the milk ducts or milk-producing lobules begin to grow abnormally. Ductal carcinoma originates in the ducts, while lobular carcinoma starts in the lobules.
Breast cancer is categorized into different types:
1. Invasive Breast Cancer – The most prevalent form.
2. Inflammatory Breast Cancer – A rare and aggressive variant.
3. Recurrent Breast Cancer – Occurs when cancer returns after initial treatment.
4. Metastatic Breast Cancer – The most severe stage, where cancer spreads beyond the breast to vital organs.
What Is HER2 Breast Cancer?
HER2 (Human Epidermal Growth Factor Receptor 2) is a gene found in normal breast cells responsible for cell growth and repair. However, when the HER2 gene mutates, it leads to uncontrolled cell division, resulting in HER2-positive breast cancer. This type of breast cancer tends to grow and spread faster but can be effectively treated with targeted therapies.
Recognizing Breast Cancer Symptoms
Although early-stage breast cancer often presents no symptoms, paying attention to the following warning signs can aid early detection:
• Swelling in the breast
• Lumps in the breast or underarm
• Nipple discharge or pain
• Changes in nipple appearance, such as inversion or rash formation
• Unusual redness, scaliness, or swelling of the breast skin
• Sudden breast enlargement or shrinkage on one side
Consult a healthcare professional if you notice any of these symptoms. While they do not confirm breast cancer, early medical evaluation is crucial.
