Squamous cell carcinoma is extremely rare in breast tissue. In a study reported in the "Journal of Post Graduate Medicine," only 6 cases were found over the course of 7 years, where a total of 298 malignant tumors of the breast were studied. Squamous cells are generally found on the surface of the skin and the hollow organs of the body in and around the respiratory and digestive tracts, hence the unlikelihood of this type of cancer forming in the breast tissue.
Tumor
Squamous cell carcinoma presents itself as a localized tumor on the breast, directly beneath the skin surface. According to the "Journal of Post Graduate Medicine," these tumors are not accompanied by pain in any confirmed cases, and are generally greater than 5 cm before an official diagnosis is made. These tumors can appear anywhere from 2 months to 1 year after the start of the carcinoma growth.
Skin Discoloration
There have been cases where occasional reddening of the tissue occurs on the skin above the tumor. According to the "World Journal of Surgical Oncology," this reddening of the skin can spontaneously occur and then disappear.
Swelling
According to the "World Journal of Surgical Oncology," there can be swelling around the squamous cell carcinoma tumor. The area directly surrounding the tumor can become inflamed, although it may not necessarily be sensitive to the touch.
