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.
Langerhans Cell Histiocytosis
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.
Langerhans cell histiocytosis is a type of cancer that can damage tissue or cause lesions to form in one or more places in the body. Langerhans cell histiocytosis (LCH) is a rare cancer that begins in LCH cells. LCH cells are a type of dendritic cell which fights infection. Sometimes there are mutations (changes) in LCH cells as they form. These include mutations of the BRAF , MAP2K1, RAS and ARAF genes. These changes may make the LCH cells grow and multiply quickly. This causes LCH cells to build up in certain parts of the body, where they can damage tissue or form lesions.
Laryngeal 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. Most laryngeal cancers form in squamous cells, the thin, flat cells lining the inside of the larynx. Laryngeal cancer is a type of head and neck cancer.
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.
Lip and Oral Cavity Cancer (Head and Neck Cancer)
Lip and oral cavity cancer is a type of 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. Most lip and oral cavity cancers start in squamous cells, the thin, flat cells that line the lips and oral cavity. These are called squamous cell carcinomas. Cancer cells may spread into deeper tissue as the cancer grows. Squamous cell carcinoma usually develops in areas of leukoplakia (white patches of cells that do not rub off).
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.
Lung Cancer (Non-Small Cell and Small Cell)
Non-small cell lung cancer is a disease in which malignant (cancer) cells form in the tissues of the lung. Lung cancer includes two main types: non-small cell lung cancer and small cell lung cancer. Smoking causes most lung cancers, but nonsmokers can also develop lung cancer.
There are several types of non-small cell lung cancer. Each type of non-small cell lung cancer has different kinds of cancer cells. The cancer cells of each type grow and spread in different ways. The types of non-small cell lung cancer are named for the kinds of cells found in the cancer and how the cells look under a microscope. These include:
Squamous cell carcinoma
Cancer that begins in squamous cells, which are thin, flat cells that look like fish scales. This is also called epidermoid carcinoma.
Large cell carcinoma
Cancer that may begin in several types of large cells.
Cancer that begins in the cells that line the alveoli and make substances such as mucus.
Other less common types of non-small cell lung cancer are: pleomorphic, carcinoid tumor, salivary gland carcinoma, and unclassified carcinoma.
Childhood Lung Cancer - see Unusual Cancers of Childhood
In children, the most common lung tumors are tracheobronchial tumors and pleuropulmonary blastoma.
Tracheobronchial tumors begin in the cells that line the surface of the lung. Most tracheobronchial tumors in children are benign and occur in the trachea or large bronchi (large airways of the lung). Sometimes, a slow-growing tracheobronchial tumor becomes cancer that may spread to other parts of the body.
Pleuropulmonary blastomas (PPBs) form in the tissue of the lung and pleura (tissue that covers the lungs and lines the inside of the chest). PPBs can also form in the organs between the lungs including the heart, aorta, and pulmonary artery, or in the diaphragm (the main breathing muscle below the lungs).
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.
