Some stages of life

Some life stages are more prone to the appearance of new moles. For example, adolescence is a stage exposed to great hormonal changes in which an increase in the concentration of maritime cells may appear, which are responsible for causing the appearance of moles.

Immune system depression

Another factor that can explain why new moles appear in the body is the presence of some autoimmune diseases, as well as people with some nutritional deficit. The weakness of the immune system increases the predisposition to the appearance of new moles on the body.

Intake of some medications

Several drugs have been associated with the generation of new moles on the skin, such as immunosuppressants , which are responsible for depressing the immune system. The use of some biological substances such as monoclonal antibodies, also called biological therapies , are used in patients with inflammatory diseases such as psoriasis , rheumatoid arthritis and ulcerative colitis.

• Young people under 35 years of age.
