What are the different types of breast cancer?
CTF Help Staff asked 10 months ago
1. Ductal Carcinoma In Situ (DCIS)
- Description: DCIS is a non-invasive cancer where abnormal cells are found in the lining of a breast duct but have not spread outside the duct. It's considered the earliest form of breast cancer and is highly treatable.
- Sources: American Cancer Society, National Cancer Institute
2. Invasive Ductal Carcinoma (IDC)
- Description: IDC is the most common type of breast cancer, accounting for about 80% of all cases. It starts in the milk ducts and then invades nearby tissues in the breast. Over time, IDC can spread to other parts of the body.

3. Invasive Lobular Carcinoma (ILC)
- Description: ILC begins in the milk-producing glands (lobules) and can spread to nearby tissues and other parts of the body. It accounts for about 10-15% of invasive breast cancers.
- Sources: American Cancer Society, Mayo Clinic
4. Inflammatory Breast Cancer (IBC)
- Description: IBC is a rare and aggressive form of breast cancer that causes the breast to become red, swollen, and warm. Cancer cells block lymph vessels in the skin of the breast, causing the inflammatory symptoms.
- Sources: National Cancer Institute, American Cancer Society
5. Triple-Negative Breast Cancer
- Description: This type of breast cancer does not have estrogen receptors, progesterone receptors, or excess HER2 protein. It is more common in younger women and African American women and tends to be more aggressive and harder to treat.
- Sources: American Cancer Society, BreastCancer.org
6. HER2-Positive Breast Cancer
- Description: HER2-positive breast cancer has higher levels of the HER2 protein, which promotes the growth of cancer cells. It tends to grow faster than other types of breast cancer but can be treated with targeted therapies that block HER2.
- Sources: American Cancer Society, BreastCancer.org
7. Lobular Carcinoma In Situ (LCIS)
- Description: LCIS is not considered a true cancer but indicates that there are abnormal cells in the lobules of the breast. It increases the risk of developing invasive breast cancer in either breast.
- Sources: National Cancer Institute, American Cancer Society
8. Paget's Disease of the Breast
- Description: This rare form of breast cancer starts in the ducts of the nipple and spreads to the skin of the nipple and areola. It is often associated with underlying DCIS or IDC.
- Sources: American Cancer Society, National Cancer Institute
9. Metaplastic Breast Cancer
- Description: A rare and aggressive form of breast cancer that contains a mixture of cell types. It tends to be more resistant to standard treatments.

Summary
Understanding the specific type of breast cancer is crucial for determining the most effective treatment plan. Each type can have different behaviors and responses to treatment, making tailored approaches necessary.Additional Resources

Different types of breast cancer include Ductal Carcinoma In Situ (DCIS), which is non-invasive, and Invasive Ductal Carcinoma (IDC), the most common kind. There's also Triple-Negative Breast Cancer, which doesn't respond to hormonal therapy. My sister had HER2-Positive Breast Cancer, and she took special meds that target HER2 protein. Each type is unique and affects treatment choices, so it's key to get diagnosed correctly.

There are many types of breast cancer, like Invasive Lobular Carcinoma (ILC) that begins in the milk-producing glands and spreads. My cousin had Inflammatory Breast Cancer (IBC), which made her breast swollen and red.
Another common type is HER2-Positive Breast Cancer, which grows faster but can be treated with targeted therapy. Understanding your specific type helps you and your doctor choose the right treatment.

Breast cancer comes in different types. I had Invasive Ductal Carcinoma (IDC), which starts in the milk ducts and spreads. My friend had Triple-Negative Breast Cancer, which is harder to treat but we both are fighting strong.
There's also Ductal Carcinoma In Situ (DCIS) which is early-stage and non-invasive. Each type needs different treatments, so it's important to know which one you have and talk to your doctor about the best plan.

My wife had Inflammatory Breast Cancer (IBC), which caused her breast to be red and swollen. It’s aggressive and rare. There’s also Paget’s Disease of the Breast, which starts in the ducts of the nipple. Both of these are less common but understanding these types can help in early detection and treatment. Each type has its own treatment plan, so knowing the specific type is very important for effective treatment.

I was diagnosed with HER2-Positive Breast Cancer. This type has higher levels of the HER2 protein and tends to grow faster, but targeted treatments like Herceptin have been very effective for me.
Another type is Triple-Negative Breast Cancer, which doesn't respond to hormonal therapy. It's crucial to get the right diagnosis because it influences the treatment plan significantly.
Regular check-ups and being informed about your specific type are key.
