Haemangioblastoma (pronounced he mangi oblast oma) is a rare, slow growing type of brain tumour, which is nearly always benign. It is formed in the cells that line the blood vessels in the brain.
Haemangioma (pronounced he mangi oma) is a benign tumour which develops in the blood vessels of the skin, making the skin itself appear red or pink. Some haemangioma may look like birthmarks.
Haematological Malignancies (pronounced he mat ological malign nan seas) are types of cancer that affect blood, bone marrow, and lymph nodes. They are caused by too many blood cells being made and the cells not working as they should.
Haematological Response (pronounced he mat ological) shows how well some types of cancer affecting the blood have responded to treatment. It shows that a persons blood count has gone back to more normal methods, following treatment.
Haematologist (pronounced he mat toll ogist) is a doctor who specialises treating blood disorders, including leukaemias and lymphomas.
Haematology is the study of blood and diseases of the blood.
Haematoma (pronounced he mat toe ma) is a swelling where blood has collected under the skin.
Haemoglobin is the substance which carries oxygen around the body in the red blood cells.
Hand-foot syndrome also called Palmar-plantar Erythema (pronounced palmer planter erith theme a), which just means red palms and soles. Is a side effect of some cancer treatments, including chemotherapy, where the skin on the palms of the hands and the soles of the feet goes red and peels. These symptoms clear up when the treatment is finished.
See Human Chorionic Gonadtrophin.
The organ that pumps blood received from the veins into the arteries, thereby maintaining the flow of blood throughout the body.
Helper T cells are a type of white blood cell, which stimulate B cells to make antibodies as part of the immune response.
Herbalism is using plants or herbs to help treat illness.
Heredity is the process by which characteristics are passed on, via the genes, from one generation to the next. A person inherits physical or mental characteristics or the tendency to develop particular illnesses or diseases. Half a person's genes are inherited from their mother and half from their father.
Heroin is an opiate, a powerful analgesic or pain-killer.
Hickman Line is a type of central line, sometimes called a portocath. It is a thin tube, which is put into one of the veins in a person's chest, near to the heart, through which chemotherapy drugs are gradually introduced into the blood system, known as being given intraveneously. The central line is also a means by which a doctor may take blood samples for testing. Putting in a Hickman Line is a safe procedure and it can remain in place for many months.
This is an area in a hospital where someone can receive closer medical and nursing attention than on a regular ward. This may mean there is one nurse to every one or two patients.
High Dose Chemotherapy is a course of chemotherapy using very high dose drugs. After high dose chemotherapy, it may be necessary for a bone marrow transfusion or stem cell transfusion to be carried out.
High Grade, means the cells are growing much faster than normal, so the cancer may grow more quickly and be more likely to spread than a low grade cancer.
High Grade Lymphomas are faster growing and more acute diseases than low grade. Usually they will be treated with more intensive chemotherapy treatment than low grade lymphomas. However if high grade lymphomas are treated at an early stage, it may only be necessary for them to be treated by radiotherapy.
High Grade Solid Tumours, are tumours where the cells appear similar to normal ones. This means the cancer may be slower growing and less likely to spread as high grade cancers.
Histology (pronounced hist o logy), is the study of body tissues and cells. This happens, following a biopsy, where specimens are sent to be examined under a microscope, to see whether they are normal or abnormal. In this way doctors can decide what type of body tissue it is and carry out tests to find out which type of cancer it is, if the specimen is abnormal.
Histopathologist (pronounced hiss toe path ol o gist) is a doctor specialising in diagnosis from tissue specimens.
Histopathology relates to the study of body tissue.
HIV (Human Immunodeficiency Virus) is a virus which damages the human immune system. HIV is transmitted through direct contact of a mucous membrane or the bloodstream with a bodily fluid containing HIV, such as blood, semen, vaginal fluid or breast milk.
Someone who has been tested and found to have HIV, the human immunodeficiency virus, is said to be HIV positive.
Hodgkins Disease or Hodgkins Lymphoma is a cancer of the lymphatic system, which is part of the body's natural defence mechanisms. There are two main types of lymphoma: Hodgkin's Disease or lymphoma and Non-Hodgkin's lymphoma.
See Hodgkins Disease.
Someone who can do household jobs or provide personal care, for someone who is unable to do such tasks themselves or has no one among their family or friends who can do them. Usually Social Services will arrange for a home carer, if one is needed.
See Home Carer.
This is where someone is given palliative care in their own home, rather than in a hospice. This would be the same kind of treatment as they would receive in a hospice but it would be given by specialist palliative care nurses and doctors, visiting them in their own homes.
Homoeopathy is an alternative therapy (method of treatment), where someone who is ill, is given an extremely small amount of a substance that (with a much larger amount), could produce in a healthy person, symptoms similar to those of the illness they have.
Hormone Therapy is a way of treating certain cancers that need hormones to grow. This treatment uses drugs (called anti-hormones) that stop hormones from developing and so stop the cancer from growing.
Hormones are chemical substances produced by the body, to carry out various tasks. For instance, some hormones control the way in which different cells in the body grow.
This is somewhere a person can go to cancer treatment and the relief of cancer symptoms. A hospice usually offers both day patient and in-patient care and aims to maintain the best possible quality of life, for as long as possible. This is known as palliative care.
This is a building or group of buildings where people go when they are ill or have been hurt, to be helped to get better by doctors and nurses.
Hospital Attendance is how long and how often you have to go to hospital to receive treatment.
See Hospital Records.
These tell the doctor, who is treating someone in hospital, when they have had other visits to that hospital and what treatment they received. It may also have any x-rays that have been taken and the results of tests that were done.
HCG (human chorionic gonadtrophin) is a type of protein found in the blood. The levels of HCG can be measured to check for testicular cancer.
See HIV.
Hyperplasia is where cells grow much faster than normal but the cells themselves are normal.
See Craniopharyngiomais.
