Cancer is one of the leading causes of death in the world, with almost 10 million deaths from tumors registered in 2020, according to data from the International Agency for Research on Cancer ( IARC ). For this reason, research in this field is one of the great priorities for humanity at this time. Thus, in 2022 it was been shown that some chemical products and unhealthy habits are directly linked to the risk of suffering from this disease in its different modalities.

Hair Cosmetics

Different chemical products used legally in the care and treatment of hair are closely related to the appearance of cancer. This is the case of aromatic amines in some hair dyes and tattoo inks, hair straighteners and dry shampoos, which could act as endocrine disruptors and lead to an increased risk of tumors in the bladder or uterus.

Ultra-Processed Foods

Fast food and ultra-processed food products in general are also linked to colon cancer. Likewise, obesity is also associated with a 90% risk of suffering from uterine cancer in women, while a high intake of sausage would have to do with a greater risk of suffering from colorectal cancer. Processed fiber is not spared either, since it has been shown that it can be a risk factor for people with liver problems, who could be more prone to liver cancer if they consume this type of food.

Nutritional Supplements

A nutritional supplement as popular as nicotinamide riboside, derived from vitamin B3, could be directly related to the risk of breast cancer. On the other hand, those people who consume large amounts of certain sweeteners also increase the exposure to suffer depending on what type of cancer.

Breast Implants

Recently, the Food and Drug Administration (FDA) has warned of the danger posed by breast implants, whose scar tissue could be a focus for the appearance of some rare types of cancer.


Although this risk factor has been known for years, it has recently been discovered how harmful particles in the air can trigger lung tumors, also in non-smokers. These are PM2.5, particles that cause genetic changes that appear to be related to the appearance of this type of cancer, whose symptoms often go unnoticed.
