what is cancer
group of diseases characterized by the presence of new cells growing and spreading beyond control
effect of the introduction of distilled alcohol in England in the 18th century
types of cancer - carcinomas (malignant)
cancers of epithelial tissue, cells that line outer and inner surfaces of body (skin, stomach lining, mucuous membranes)
types of cancer - sarcomas (malignant)
cancers that arise from cells in connective tissue (bone, muscle, cartilage)
types of cancer - leukemias (malignant)
cancer that originates in the blood or blood forming cells (stem cells in bone marrow)
types of cancer - lymphoma (malignant)
cancer of lymphatic system
risk factors of cancer
-radiation, asbestos, pesticides, pollution
-smoking
-diet, consumption of preserved meats
-alcohol
-sedentary lifestyle, obesity
-ultraviolet light exposure
-unsafe sexual behavior
-advancing age
-family history and genetics

effects of the 18th amendment
causes of cancer deaths
etiologies of cancer
death rates for types of cancer
-lung cancer: 22% of all cancer deaths
-breast cancer
-30 % women
-colorectal cancer: 2nd leading cause of cancer death in US (50% of all US cancer deaths)
-liver cancer (3.6%)
rates of cancers in ethnic groups
-African Americans: High incidence for most cancer (greater death rate)
-diagnosis comes at a later stage (lower survival rates)
-Hispanic, Asian, and Native Americans have lower rates than African and European Americans for cancer sites and 4 most common cancers
-Asian Americans: higher mortality rate for stomach and liver cancer
Ethnicity and alcohol use/abuse rates
relationship of BRCA genes to breast cancer
-mutated form of BRCA1: 7x more likely to develop breast cancer
-form of breast cancer involving BRCA1 and BRCA2: responsible for no more than 10% of breast cancer cases
-5-10% of cancer cases due to genetic variations
-BRCA2 mutation: greater risk for alcohol induced breast cancer
side effects of cancer treatment
-fear, anxiety, loss of hair, depression, fatigue
-radiation: burns, hair loss, vomiting, fatigue, sterility
best types of social support for cancer patients
-social support comes from health care professionals, family, friends, support groups
-health care professionals: instrumental support
-family and friends: emotional support
-cancer patients have better odds of survival if married (medical adherence, emotional support)
what is liver cirrhosis

mortality rates for cancers
