Breast Cancer Diagnosis and Treatment

What about antiperspirants or deodorants as causes of breast cancer?

Research has shown that parabens (a preservative used in deodorants) can build up in breast tissues. However, this study did not show that parabens cause breast cancer or that the parabens (which are found in many other products) were linked to the use of deodorants.

A 2002 study did not show any increased risk for breast cancer in women using an underarm deodorant or antiperspirant. A 2003 study showed an earlier age for breast cancer diagnosis in women who shaved their underarms more frequently and used underarm deodorants.

More research is needed to give us the answer about a relationship between breast cancer and underarm deodorants and blade shaving.

What are breast cancer symptoms and signs?

The most common sign of breast cancer is a new lump or mass in the breast. In addition, the following are possible signs of breast cancer:

  • Thickening or lump in the breast that feels different from the surrounding area
  • Inverting of the nipple (as a change from previous appearance)
  • Nipple discharge or redness (especially any bloody discharge)
  • Breast or nipple pain
  • Swelling of part of the breast or dimpling
  • Changes in the skin of the breast
