Malignant tumor symptoms (Characteristic And Types Of Tumor)

Tumor or Tumour is the name for solid neoplasms or lesions formed by the growth of body cells that are not supposed to, which is similar to simtoma swollen. Tumors derived from the Latin word tumere in which means "swelling". Growth can be classified as malignant (malignant) or benign (benign).

Malignant tumors are called cancer. Cancer has the potential to invade and destroy adjacent tissues and create metastases. Benign tumors do not invade nearby tissue and spread the seed (metastasis), but may locally grow to be big. They usually do not come back after removal by surgery.

Based on the initial tissue, tumors can be divided into:

Tumors of epithelial origin.
squamous epithelium: squamous cell papilloma, squamous cell carcinoma
transitional epithelium: transitional cell papilloma, transitional cell carcinoma
basal cell (only in the skin): basal cell carcinoma
glandular epithelium: adenoma, Cystadenoma, adenocarcinoma
tubules epithelium (kidney): renal tubular adenoma, renal cell carcinoma (tumor Grawitz)
hepatocytes: hepatocellular adenoma, hepatocellular carcinoma
bile ducts epithelium: cholangiocellular adenoma, cholangiocellular carcinoma
melanocytes: melanocytic nevus, malignant melanoma
Tumors of mesenchymal origin:
tissue related:
fibroma, fibrosarcoma
myxoma, myxosarcoma
chondroma, chondrosarcoma
osteoma, osteosarcoma (osteogenic sarcoma)
lipoma, liposarcoma
muscle:
leiomyoma, leiomyosarcoma
rhabdomyoma, rhabdomyosarcoma
endothelium:
hemangioma (capillary h., cavernous h.), glomus tumor, hemangiosarcoma, Kaposi sarcoma
lymphangioma, lymphangiosarcoma
Tumor blood cells:
hematopoietic cells: leukemia
lymphoid cells: non-Hodgkin's lymphoma, Hodgkin's lymphoma
Germ cell tumors:
Teratoma (mature teratoma, immature teratoma)
