5. Swollen lymph nodes in the armpit
Some patients with breast cancer that has spread to the lymph nodes may have no symptoms in the breast or changes in the structure of the breast, but they feel something unusual under their arm. This may mean that cancer from the breast has traveled to the axillary lymph nodes, which are in the armpit. Affected nodes may also be in the lower part of the neck if the cancer is a little more advanced. Cancer cells often use the lymphatic system to invade distant organs.
It’s important to also remember that not all breast lumps are signs of cancer, a fact that underscores why it’s important for women to be familiar with the look and feel of their breasts. “Have an awareness of your breasts,” Dr. Lynch says. “You need to touch them to be aware. Breast self-awareness is the terminology now used instead of a self-breast exam.”
6. Breast pain with no lump
Breast pain when there’s no visible or physical lump may still cause concerns about breast cancer. Breast pain, also known as mastalgia, can be associated with many conditions, including:
- Hormonal changes during menstrual cycle
- Water retention, which may also occur during menstruation
- Breast injury
- Breast infection
- Pregnancy
- Breastfeeding
- Medication side effect
- Breast cancer
Breast soreness may be chronic in some women, but it typically resolves on its own.
