|What is tumor?|
A tumor, also known as a neoplasm, is an abnormal mass of tissue which may be solid or fluid-filled. A tumor does not mean cancer which mean tumors can be benign (non-cancerous), pre-malignant (pre-cancerous), or malignant (cancerous). There are many different types of tumors and a variety of names for them which is their names usually reflect their shape and the kind of tissue they appear in. Put simply, a tumor is a kind of lump or swelling, it does not necessarily pose a health threat.
|What is Benign Tumor?|
A tumor or benign tumor cannot metastasize and it cannot spread. Examples include uterine fibroids and moles. Benign means it is non-progressive, it remains as it is. Most benign tumors are not harmful to human health. Even though they are not cancerous, some may press against nerves or blood vessels and cause pain or other negative effects. Benign tumors of endocrine tissue may result in the excessive production of some hormones.
|What are type of Benign Tumor?|
This is types of tumor that arise from glandular epithelial tissue. Epithelial tissue is the thin membrane that covers gland, organs and other structures in the body. A polyp in the colon is a type of adenoma.
- Fibroids (fibromas)
This is the types of benign tumors that grow on fibrous or connective tissue of any organ in the body. Uterine fibroids are common. Uterine fibroids can cause vaginal bleeding, pelvic pain or discomfort, and urinary incontinence.
The fibroma durum (hard fibroma) is made up of many fibers and few cells. The fibroma molle (soft fibroma) is made up of several loosely connected cells and less fibroid tissue. Soft fibroma is usually found in the armpits, groin, neck and eyelids.
Hemangioma is a benign tumor which consists of a collection of too many blood cells. They can sometimes be seen on the surface of the skin and are colloquially called strawberry marks. The majorities of hemangiomas appear at birth and gradually go away after some months or years. These types of tumors do not usually require any treatment. Other than that, if the patient’s ability to eat hear or see, the doctor may recommend treatment with corticosteroid. If the patient is over 10 years of age, they are more commonly removed today using laser surgery.
Lipoma is the most common form of soft-tissue tumor. Lipomas consist of adipose tissue (fat cells). Most of them are very small, painless, soft to the touch, and generally movable.
|What is Malignant Tumor?|
Malignant tumors are cancerous tumors; they tend to become progressively worse, and can potentially result in death. Malignant tumors is grow fast rather than benign tumor, ambitious and they seek out new territory, and they spread (metastasize). Metastasize is a malignant tumors invade nearby cells, and then the cells near those, and spread. Some cells can break off from the tumor and spread to various parts of the body through the bloodstream or the lymphatic system, and establish themselves anywhere in the body, and form new malignant tumors.
|What are types of malignant tumor?|
These types of tumor are derived from the skin or tissues that line body organs (epithelial cells). Carcinoma can be, for example, of the stomach, prostate, pancreas, lung, liver, colon or breast.
These are tumors that start off in connective tissue such as cartilage, bones, fat and nerves. They originate in the mesenchymal cells outside the bone marrow. The majority of sarcoma tumors are malignant.
- Lymphoma/ Leukemia
This types of cancer that arise from the blood forming (hematopoietic) cells that originate in the marrow and generally mature in the blood or lymph nodes. Leukemia accounts for 30% of childhood cancers. Leukemia is thought to be the only cancer where tumors are not formed.
- Germ cell tumor
These are tumors that arise from a germ cell, pluripotent cells (cells than can turn into any kind of cell). Germ cell tumors most commonly present in the ovary or testicle. The majority of testicular tumors are germ cell ones. Less commonly, germ cell tumors may also appears in the brain, abdomen or chest.
Tumors derived from embryonic tissue or immature cells. These types of tumors are more common in children than adults. For example, medulloblastoma and glioblastoma are kinds of brain tumors, retinoblastoma is a tumor in the retina of the eye, osteoblastoma is a type of bone tumor, white a neuroblastoma is a tumor found in children of neural origin.
