Yes. There are several different forms breast cancer can take. The most common include:
Invasive breast cancer
This is where the cancer cells have spread through the lining of the ducts and into the surrounding tissue. While not always aggressive, it does have the potential to spread.
Invasive lobular breast cancer
This type of breast cancer starts in the cells that line the lobules (the glands that produce breastmilk) before spreading into the surrounding tissue.
Triple negative breast cancer
Aggressive, but thankfully relatively rare, triple negative cancer is so-called because it lacks receptors for oestrogen, progesterone and the protein HER2. Many effective cancer treatments work by targeting these receptors, which can make this cancer difficult to treat.
Inflammatory breast cancer
Inflammatory breast cancer is a rare form of breast cancer that grows along the lymph vessels in the skin of the breast, causing swelling and redness which make the breast look inflamed.
Angiosarcoma of the breast
This cancer develops in the soft tissue and, while aggressive and quick to spread, is very rare.
Ductal carcinoma in situ (DCIS)
DCIS is when the cancer cells grow inside the milk ducts. “In situ” means they haven’t yet spread into the surrounding breast tissue.
Male breast cancer
Male breast cancer can develop in the small amount of breast tissue men have behind their nipples. It’s both rare and most commonly seen in men over 60, though it can affect younger men too.
