Cancer Ribbons / Cancer Awareness Ribbons
There are more than 100 types of cancer. Types of cancer are usually named for the organs or tissues where the cancers form, but they also may be described by the type of cell that formed them.
Hairy Cell Leukemia
Leukemia is a broad term for cancers of the blood cells. The type of leukemia depends on the type of blood cell that becomes cancer and whether it grows quickly or slowly. Leukemia occurs most often in adults older than 55, but it is also the most common cancer in children younger than 15. Hairy cell leukemia is a cancer of the blood and bone marrow. This rare type of leukemia gets worse slowly or does not get worse at all. The disease is called hairy cell leukemia because the leukemia cells look "hairy" when viewed under a microscope.
Head and Neck Cancer
Head and neck cancers include cancers in the larynx, throat, lips, mouth, nose, and salivary glands. Tobacco use, heavy alcohol use, and infection with human papillomavirus (HPV) increase the risk of head and neck cancers. Oral cavity, pharyngeal, and laryngeal cancers may be referred to as head and neck squamous cell cancers. Head and neck squamous cell cancers most commonly arise from the mucosal surfaces lining the oral cavity, pharynx, and larynx. Pharyngeal squamous cell cancers are further categorized into nasopharyngeal, oropharyngeal, and hypopharyngeal cancers on the basis of anatomical landmarks.
Heart Tumors, Childhood - see Unusual Cancers of Childhood
Most tumors that form in the heart are benign (not cancer). Before birth and in newborns, the most common benign heart tumors are teratomas. An inherited condition called tuberous sclerosis can cause heart tumors to form in a fetus or newborn. Malignant tumors that begin in the heart are even more rare than benign heart tumors in children.
Hepatocellular (Liver) Cancer
Liver cancer includes hepatocellular carcinoma (HCC) and bile duct cancer (cholangiocarcinoma). Risk factors for HCC include chronic infection with hepatitis B or C and cirrhosis of the liver.
Histiocytosis, Langerhans Cell
Langerhans cell histiocytosis (LCH) is a rare blood cancer that forms when a type of white blood cell called Langerhans cells becomes abnormal and grows in different parts of the body. LCH is most common in young children but can occur at any age.
Lymphoma is a broad term for cancer that begins in cells of the lymph system. The two main types are Hodgkin lymphoma and non-Hodgkin lymphoma (NHL). Hodgkin lymphoma can often be cured. The prognosis of NHL depends on the specific type. Hodgkin lymphoma is a type of cancer that develops in the lymph system, part of the body's immune system. The immune system protects the body from foreign substances, infection, and diseases.
Hypopharyngeal Cancer (Head and Neck Cancer)
Head and neck cancers include cancers in the larynx, throat, lips, mouth, nose, and salivary glands. Tobacco use, heavy alcohol use, and infection with human papillomavirus (HPV) increase the risk of head and neck cancers. The hypopharynx is the bottom part of the pharynx (throat).
