Full Answer

Individuals with certain genetic syndromes, such as neurofibromatosis type 1 and multiple endocrine neoplasia type 1, are at a greater risk of developing carcinoid tumors as are those with stomach conditions that reduce stomach acid, as confirmed by Web MD. Women are more likely than men to develop the tumors, and African-American individuals of both genders are at a greater risk than are Caucasians. Due to their slow growth, doctors often catch carcinoid tumors before they have a chance to cause symptoms or metastasize to other organs.

Smoking is the leading cause of cancer and cancer-caused deaths in the nation as well as the No. 1 cause of all premature, preventable deaths, as stated by the National Cancer Institute. Smokers may develop cancer in the lungs, mouth, throat and larynx as well as in the cervix, esophagus, stomach, kidney and pancreas. They may also develop aortic aneurysms, heart disease and stroke. At least 69 of tobacco smoke's 250 harmful chemicals are known to cause cancer, and several others are suspected carcinogens.
