Generally, cancer that detect in the breast is formed in the mammary glands (lobules) or tracts of the breast, which transports milk from the glands to the nipple. Fatty or breast fibrous compound tissue can also be main spots for cancer cells. In some cases cancer cells can reach to the lymph nodes under your arms and spread to different parts of the body. You will be surprise to know that your regular deodorants may cause cancer. So, today in this article we will tell you about how deodorants can also lead to breast cancer.

What is Breast Cancer?

According to The World Health Organization (WHO), breast cancer is the most common cancer women have. Statistics show that breast cancer affects about 2.3 million women worldwide every year. According to WHO, the number of women dying of breast cancer in 2020 alone was 685,000.(1)

This is about 15 per cent of cancer deaths among the female population. Breast cancer is a condition when breast cells are divided due to changes in some genes and begin to grow and spread uncontrollably.

Types of Breast Cancer.

There are different types and stages of breast cancer. In addition, it can also affect men, although there are very few such cases. There are broadly two types of breast cancer: invasive (rapidly transmitting) and non-invasive (slowly spreading). 80% of breast cancer is caused by invasive ductal carcinoma.

In this type, cancer reaches to breast fat through duct walls. While in non-invasive type the cells of breast cancer do not go beyond the origin of tissue. Apart from these, there are two other types of breast cancer, although they are very rare. Such as inflammatory breast cancer.

The cases reduced to less than 1 per cent but it spreads rapidly and also has the highest risk of death of women. The fourth type of breast cancer is pagete’s disease. In this type, the area of the nipple turns completely black. The probability of such type of cancer is less than 5 per cent.

Deodorants Cause Breast Cancer- Myth or True?

Recently an email rumored was circulated that using deodorants can cause breast cancer. Few people are saying its a myth and few others suggesting it’s true. But according to the research it can be said that, there is no concrete epidemiological studies in the medical literature which supports this. But few of the studies support this evidence. (3)

A study was conducted on 2002 over 813 women with breast cancer and 793 normal women. There the researcher could not find any link with the aspirants.

Whereas, a study published on 2003 stated that women particularly who shaved their underarms prior to apply deodorants has been found that they are prone to develop breast cancer.

The fact is cancer causing agents are absorbed through the razor nicks of shaved underarm. Thereby, these agents gets deposited in lymph nodes of underarm and are difficult to flush out through sweats as antiperspirants suppress it. Thus, it lead to high toxins in the body which lead to develop cancer by mutating the cells.(4)

However, there are very less epidemiological studied which support this evidence.

Bottom Line.

Therefore, it can be said breast cancer is one of the deadly disease and need to be diagnosed properly to avoid huge damage. However, as per the recent fact regarding deodorants cause breast cancer, it is advisable to avoid overdose of deodorants. If you find any kind of irritations or itching on the skin consult with doctor immediately.
