    Adenomas
    Adenomas are tumors that arise from glandular epithelial tissue, the thin membrane that covers glands, organs, and other structures in the body.

    A polyp in the colon is a type of adenoma. Other examples s:

    parathyroid adenoma
    eosinophilic adenoma
    basophilic adenoma
    bile duct adenoma
    chromophobe adenoma
    fibroadenoma
    hepatic adenoma
    Adenomas do not start as cancers. However, they can change and become cancerous, taking the form of adenocarcinomas.

    Fibroids, or fibromas
    Fibroids are benign tumors that can grow on the fibrous or connective tissue of any organ. Uterine fibroids are common and can cause vaginal bleeding, pelvic pain or discomfort, and urinary incontinence. They can be "soft" or "hard" depending on the proportion of fibers to cells.

    There are many types of fibroma, including angiofibroma, dermatofibroma, and ossifying and non-ossifying fibroma.

    Some fibromas can cause symptoms and may require surgical removal. In rare cases, fibroids can change and eventually become cancerous. They are then called fibrosarcomas.

    Hemangiomas

    Hemangiomas are benign tumors that consist of excessive blood cells.

    They can sometimes be seen on the surface of the skin and are known as strawberry marks. The majority of hemangiomas appear at birth and gradually go away after some months or years.

    Hemangiomas do not usually require any treatment. If they affect the ability of an individual to eat, hear, or see, the doctor may recommend treatment with corticosteroids.

    If the patient is over 10 years of age, they are more commonly removed using laser surgery.

    Lipomas
    Lipomas are the most common form of soft-tissue tumor.

    They consist of fat cells. Most of them are very small, painless, soft to the touch, and generally movable. They are more common among people aged over 40 years. Experts disagree on whether lipomas can change and become cancerous.

    There is a range of lipomas, including:

    angiolipoma
    myelolipoma
    fibrolipoma
    spindle cell lipoma
    hibernoma
    atypical lipoma
    Premalignant
    This type of tumor requires close monitoring

    Examples of premalignant growths include:

    Actinic keratosis
    Also known as senile keratosis or solar keratosis, this is a premalignant growth consisting of patches of skin that turn crusty, scaly, and thick.

    Fair-skinned people are more at risk of developing these types of growths, especially those who are overexposed to sunlight.

    Actinic keratoses are seen as potentially premalignant, because around 20 percent of them progress to squamous cell carcinoma. Doctors usually recommend treating them because of this. Continuous exposure to the sun increases the risk of malignancy.

    Cervical dysplasia
    This is a change in the normal cells lining the cervix.

    The growth can be premalignant and is at risk of developing into cervical cancer.

    Cervical dysplasia is diagnosed with a PAP smear. It is most common in women aged 25 to 35 years and may be removed with freezing techniques or by removing the cone of tissue from the cervix.

    Metaplasia of the lung
    These growths occur in the tubes that carry air from the windpipe into the lung, or the bronchi.

    The bronchi are lined with glandular cells, which can change and become squamous cells. Metaplasia of the lung is most commonly caused by smoking.

    Leukoplakia
    Thick, white patches can form on the gums, the bottom of the mouth, the insides of the cheeks, and, less commonly, on the tongue. They cannot be scraped off easily.

    Experts believe smoking or chewing tobacco is the main cause. Although Leukoplakia is rarely dangerous, a small percentage can eventually become cancerous. Many mouth cancers occur near areas of leukoplakia.

    The condition usually clears up when people quit smoking. Quitting both alcohol and tobacco together has better results. The patches can be removed using a laser, a scalpel, or a cold probe that freezes the cancer cells.

    Malignant
    [Dividing cancer cells]
    Malignant tumors divide and spread rapidly, colonizing new areas.
    Malignant tumors are cancerous tumors that can potentially result in death.

    Unlike benign tumors, malignant ones grow quickly, and can spread to new territory in a process known as metastasis.

    The abnormal cells that form a malignant tumor multiply at a faster rate.

    The cancer cells that metastasize are the same as the original ones. If a lung cancer spreads to the liver, the cancer cells now growing in the liver are still lung cancer cells. They have, however, acquired the ability to invade other organs.

    Different types of malignant tumor are made up of specific types of cancer cells, including:

    Carcinoma: These tumors are formed from epithelial cells. For example, carcinomas can occur in the stomach, prostate, pancreas, lung, liver, colon, or breast. Many of the most common tumors are carcinomas, especially among older adults.

    Sarcoma: These tumors start in connective tissue, such as cartilage, bones, fat, and nerves. They originate in the cells outside the bone marrow. The majority of sarcomas are malignant.

    Germ cell tumor: These are tumors made from the cells that give life, sperm and egg cells. Germ cell tumors most commonly occur in the ovaries or testicles. The majority of testicular tumors start from germ cells. Less commonly, germ cell tumors may also appear in the real brain tumor, abdomen or chest.

    Blastoma: Tumors formed from embryonic tissue or developing cells are known as blastomas and are more common in children than adults. Examples include medulloblastoma and glioblastoma, types of real brain tumor tumor, retinoblastoma, a tumor in the retina of the eye, osteoblastoma, a type of bone real brain tumor, and neuroblastoma, a tumor of the nervous system found in children.

    Diagnosis
    To diagnose a tumor and decide whether a tumor is malignant or not, a sample must be taken by a surgeon or an interventional radiologist, sent to a laboratory, and examined under a microscope by a pathologist.

    This sample is called a biopsy. There are three different types of biopsy:
