  2. Cutaneous squamous-cell carcinoma - Wikipedia

    en.wikipedia.org/wiki/Cutaneous_squamous-cell...

    Cutaneous squamous-cell carcinoma is the second-most common cancer of the skin (after basal-cell carcinoma, but more common than melanoma). It usually occurs in areas exposed to the sun. Sunlight exposure and immunosuppression are risk factors for SCC of the skin, with chronic sun exposure being the strongest environmental risk factor. [26]

  3. Cancer cell - Wikipedia

    en.wikipedia.org/wiki/Cancer_cell

    Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because of ...

  4. Hodgkin lymphoma - Wikipedia

    en.wikipedia.org/wiki/Hodgkin_lymphoma

    Hodgkin lymphoma (HL) is a type of lymphoma in which cancer originates from a specific type of white blood cell called lymphocytes, where multinucleated Reed–Sternberg cells (RS cells) are present in the patient's lymph nodes.

  5. List of cancer types - Wikipedia

    en.wikipedia.org/wiki/List_of_cancer_types

    The following is a list of cancer types. Cancer is a group of diseases that involve abnormal increases in the number of cells, with the potential to invade or spread to other parts of the body. [1] Not all tumors or lumps are cancerous; benign tumors are not classified as being cancer because they do not spread to other parts of the body. [1]

  6. Carcinoma - Wikipedia

    en.wikipedia.org/wiki/Carcinoma

    Carcinoma is a malignancy that develops from epithelial cells. [1] Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells originating in the endodermal, mesodermal [2] or ectodermal germ layer during embryogenesis.

  7. Melanoma - Wikipedia

    en.wikipedia.org/wiki/Melanoma

    This early stage of the disease is called the radial growth phase, when the tumor is less than 1 mm thick, and spreads at the level of the basal epidermis. [41] Because the cancer cells have not yet reached the blood vessels deeper in the skin, it is very unlikely that this early-stage melanoma will spread to other parts of the body.

  8. Cancer - Wikipedia

    en.wikipedia.org/wiki/Cancer

    Cancers are caused by a series of mutations. Each mutation alters the behavior of the cell somewhat. Cancer is fundamentally a disease of tissue growth regulation. For a normal cell to transform into a cancer cell, the genes that regulate cell growth and differentiation must be altered. [95] The affected genes are divided into two broad categories.

  9. Circulating tumor cell - Wikipedia

    en.wikipedia.org/wiki/Circulating_Tumor_Cell

    An illustration depicting primary tumor (in the form of tumor microenvironment) and the circulating tumor cells. A circulating tumor cell (CTC) is a cancer cell from a primary tumor that has shed into the blood of the circulatory system, or the lymph of the lymphatic system. [1]
