[|Human|] If Allergy is an overreaction of the immune system to a foreign substance such as pollen, dust mites, mold spores, food, insect stings, medicines etc. My Question is .. if I take antihistamine drug will it affect my immune system , that cancer cells will appear or grow ? Thanks :)
[|AI|]  HI, thanks for using Chat Doctor Histamine is one of the chemicals made in the body in response to an allergic reaction. This chemical is involved in causing some allergy symptoms. Histamine is not involved in other aspects of the immune system. The immune system is vast and there are different types of cells that involved in an immune response. The part of the immune system involved in allergies is different from the parts that-fight viral infections, fight bacterial or parasites, reduce cell multiplying and cancer. So, no, the use of anti histamines would not affect the aspect of the immune system involved in suppression abnormal cell growth. I hope this helps
