Breast cancer is a cancer, which forms in the cells of the breasts. Breast cancer is the second most common cancer diagnosed in women. Breast cancer can develop in both men and women; however, it is much more common in women. Some of the common symptoms of breast cancer can be breast lump, change in size of the breast, peeling, scaling or crusting of the pigmented area of skin around the nipple, changes in skin over the breast, redness or pitting of the skin over the breast.

Considerable support for breast cancer awareness has helped to create advances in its diagnosis and treatment. The survival rates have increased for breast cancer and the number of deaths linked with this disease is progressively declining because of the factors as detection at an early stage, a better understanding of the diseases and a new modified approach to treatment. Also, the studies were done by the researchers to show the benefits of squalene for breast cancer also helped the people to prevent the development of breast cancer.

Squalene is an excellent scavenger of free radicals; thus it protects cells and organs from auto-oxidative damages. On the other side, most antioxidants have side effects and they fail to get approval from certifying agencies. Hence, it is crucial to use antioxidants which are having essential characteristics as better safety profile and good oral availability. Squalene is among those antioxidants that match these characteristics.

Animal studies done in recent times shown that squalene in sebum play a protective role against the production of hydrocarbon carcinogens in the skin and also prevented the damages caused by radiation therapy. As it is a natural product, its consumption has no side effects, it is harmless. Several experimental studies have shown that the squalene is an excellent detoxifying agent against toxic and carcinogenic chemicals like hexachlorobiphenyl, theophylline, Phenobarbital, hexachlorobenzene, arsenic and strychnine.

It was found that those women who consume large quantities of olive oil have a much lesser risk of developing breast cancer. Therefore squalene is now being used in cancer patients as a prophylactic agent after irradiation treatment. The mechanism behind the function of squalene as prophylactics agent for cancer is its ability to reduce mutated ras oncogene activation. Ras oncogene is a family of genes which make proteins associated with cell signalling pathways that manage cell growth and cell death.

Thus it is evident that the consumption of squalene supplements can help to prevent the occurrence of breast cancer.
