The American Cancer Society says that sometimes a breast cancer can spread to lymph nodes under the arm or around the collarbone and cause a lump or swelling there, even before the original tumor in the breast tissue is large enough to be felt.¹ Therefore any pain or discomfort in the armpit is something that should definitely be tested and you should also be aware of the other causes of armpit pain that is include in warning breast cancer symptoms.There is sometimes a hard lump that appears in the armpit and tissue surrounding it that won’t move when touched. There may also be tissue that is thicker and dense when compared with the other armpit. A sore spot could indicate many things that aren’t a tumor. But it never hurts to be safe and get a medical evaluation, as the underarm tissue does have a close connection to breast tissue.

One of the most common locations of breast cancer is beneath the nipple. The presence of a cancerous lesion may cause changes in appearance and sensitivity of the nipple. Different texture, color and shape might occur. The nipple may also feel much more tender and have an unusual texture. Some women describe a lack of sensitivity within the nipple, especially during intimate relations.

The American Cancer Society mentions nipple pain, nipple retraction (nipple that turns inward) and redness, scaliness or thickening of the nipple as possible Breast Cancer Symptoms. Itching, a burning sensation, or ulceration in the nipple is include in Breast Cancer Symptoms.A discharge of clear liquid, blood, or milk that doesn’t happen during breast feeding might also be a sign of breast cancer.unusual discharge from the nipple is usually caused by benign conditions, but may also indicate breast cancer in some cases, in which the discharge can be clear, bloody, or another color.
