Cancer Tumors

Cancer Tumors

How ill If There's Disease in the Human Body. How ill, if we have a cancer tumor. Surely we feel is the pain and discomfortIf our bodies are affected by cancer, was just how illIn developed countries, such as Western Europe and the United States, cancer is the second leading cause of death after cardiovascular disease ( heart ). In Indonesia, the cancer became the sixth leading cause of death, after infection, malnutrition, accidents, cardiovascular and degenerative diseases, as well as hormones or immunological abnormalities

Until now, people often confuse the understanding of tumor and cancer. Though they are different. Tumor tissue cells are wild form of a lump or swelling in the body. Slow tumor progression and remain in one location, but definitely and continue to grow. If the lump appears in the wild parts of our bodies, whether ill or not, should watch out because the lump was probably a tumor.

Tumors are not so dangerous for health. Tumor progression could be caused by the growth of new tissue or fluid collection, such as cysts and lumps that contain blood from the impact. Initially benign tumors if not treated properly will become inflamed and is not likely to turn into malignant tumors, aka cancer. Benign tumors usually grow slowly and only in one place. These tumors can continue to grow, but does not spread to other body parts and rarely interfere with health. No wonder if someone who has many years of suffering from a tumor in the back did not feel distracted and never felt any ill.

In contrast to tumors, cancer is the body's tissue cells that grow abnormally, but continued to divide rapidly and uncontrollably. Cancer is not contagious, except for liver cancer or hepatitis C. In the meantime, there is an opinion stating that cancer is caused by a virus, but the virus is different from the virus in other infectious diseases. Cancer cells will continue to grow to infiltrate the surrounding tissue, then spread to more distant places through blood vessels and lymph vessels. Cancer cells have spread in many places very difficult to treat. In fact, medically had no hope of recovery. Really how ill.

Tumor is the name for neoplasm or lesion formed by a dense 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 "swollen".  Growth can be classified as malignant or benign.

Malignant tumors are called cancer. Cancer has the potential to invade and destroy adjacent tissues and create metastases. Benign tumors do not invade adjacent tissue and spread the seed (metastasize), but can be grown locally to be great. They usually did not recur 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 (skin only): basal cell carcinoma.
  • Glandular epithelium: adenoma, cystadenoma, adenocarcinoma.
  • Tubules epithelium (kidney): renal tubular adenomas, renal cell carcinoma (Grawitz tumor).
  • Hepatocytes: hepatocellular adenoma, hepatocellular carcinoma.
  • Bile ducts epithelium: cholangiocellular adenoma, cholangiocellular carcinoma.
  • Melanocytes: Melanocytic nevus, malignant melanoma.
*  Tumors of mesenchymal origin:
     -  Tissue related to:
  • fibroma, fibrosarcoma
  • myxoma, myxosarcoma
  • chondroma, chondrosarcoma
  • osteoma, osteosarcoma (osteogenic sarcoma)
  • lipoma, liposarcoma
     - Muscle:
  • leiomyoma, leiomyosarcoma
  • rhabdomyoma, rhabdomyosarcoma

     - Endothelium:
  • hemangioma (capillary h., h. cavernous), glomus tumors, 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)
Tumors caused by mutations in the DNA of cells. An accumulation of mutations required for tumor can arise. Mutations that activate oncogenes or tumor suppress gene anchoring may eventually lead to tumors. Cells have mechanisms that repair DNA and other mechanisms that cause the cell to destroy itself by apoptosis if DNA damage is too severe. Mutations that holds the genes for these mechanisms can also cause cancer. A single mutation in one gene retaining Oncogene or tumor is usually not sufficient cause tumors. A combination of a number of mutations required.


DNA microarrays can be used to determine whether oncogene or tumor barrier genes have been mutated. In the future the possibility of a tumor can be treated better by using DNA microarrays to determine the detailed characteristics of the tumor.


Aging causes more mutations in their DNA. This means the "prevalence" strongly increased tumor along with aging. This is also the case in which parents who have tumors, most of these tumors are malignant tumors. For example, when a 20-year-old woman had a tumor in his chest most likely these tumors are benign. However, if the 70-year-old women most likely to eat these tumors are malignant.
