Health Insurance Portability and Accountability Act (HIPAA) is legislation that regulates the way healthcare providers are able to share your personal health information and ensures you access to your health records.

Heat therapy, also called hyperthermia, is the application of very high temperatures to destroy cancer cells. Heat therapy, including radiowaves, microwaves, and other forms of energy, can be applied internally, with needles or probes inserted directly into the tumor, or externally.

Hematopoietic growth factors are substances in the immune system that stimulate the growth of new blood cells.

Holistic describes an approach to health and medicine that addresses all aspects of a person's well-being, including the physical, psychological, emotional, and spiritual aspects.

Homeopathy, following the philosophy of like-cures-like, is the practice of using miniscule doses of active natural substances to stimulate the immune system and promote internal balance to restore health.

Hormone therapy is a conventional medical treatment that blocks the effects of hormones on the body, inhibiting the growth of hormonesensitive cancers.

Hormone receptors are proteins, found in some but not all cancer cells, that allow a specific hormone, such as estrogen, to attach to the cells and fuel their growth.

Hormone-receptive cancers are cancers that rely on a specific hormone, such as testosterone or estrogen, for growth. They can often be treated by blocking the supply of that hormone.

Hospice care is end-of-life treatment that focuses on relieving symptoms, maintaining quality of life, and preserving dignity, rather than curing illness.

Human leukocyte antigen (HLA) typing is a blood test used to determine whether a potential transplant donor and recipient are genetically compatible and likely to be a good match.

Human papillomavirus (HPV) is a sexually transmitted infection that can cause cervical cancer in women.

Hybridoma are laboratory-produced hybrid cells used in immunotherapy. They're created by injecting mice with a specific antigen and then harvesting the antibody-producing cells the mice create and fusing them with cancerous immune cells. Because the fused cells are cancer cells, they reproduce rapidly, creating large quantities of cancer antibodies. This technology enables doctors to produce large amounts of specific antibodies for use in monoclonal antibody therapy.

Hyperthermic perfusion is a cancer treatment using a heated liquid containing chemotherapy agents either to bathe the affected tissues or infuse the tumor’s blood vessels.
