Many local organizations offer a variety of practical and support services to people with cancer. Support can take the form of support groups, counseling, advice, financial assistance, transportation to and from treatment, films or information about cancer. Neighborhood organizations, local health care providers, or area hospitals may have resources or services available.
Counseling can provide emotional support to cancer patients and help them better understand their illness. Different types of counseling include individual, group, family, peer counseling, bereavement, patient-to-patient, and sexuality.
Many governmental and charitable organizations have been established to help patients cope with cancer. These organizations often are involved in cancer prevention, cancer treatment, and cancer research
Cancer is responsible for about 25% of all deaths in the U.S., and is a major public health problem in many parts of the world. In the U.S., lung cancer causes about 30% of cancer deaths but only about 15% of new cancer cases; the most commonly occurring cancer in men is prostate cancer (about 25% of new cases) and in women is breast cancer (also about 25%). Cancer can also occur in young children and adolescents, but it is rare (about 150 cases per million in the U.S.), with leukemia being the most common.[85] In the first year of life the incidence is about 230 cases per million in the U.S., with the most common being neuroblastoma.[86]
Over a third of cancer deaths worldwide are due to potentially modifiable risk factors, which are headed by tobacco smoking, alcohol use, and diets low in fruit and vegetables. In developed countries overweight and obesity is also a leading cause of cancer, and in low-and-middle-income countries sexual transmission of human papillomavirus is a leading risk factor for cervical cancer.
