Benign Tumors vs. Malignant Tumors - Differences

Colon cancer. Statistics

The word tumor can have a generic and a specific meaning. In one generic sense any increase in tumor volume is well circumscribed and rounded to an organ or tissue. This meaning is closely related to that of swelling.

In specific sense tumor is a "neoplasm" of one or several tissues whose cells reproduce "atypical" normal tissue structure is implanted in the tumor. The neoformation is developed with a more or less rapid growth in complete independence and autonomy of our bodies at risk entering the vital forces of the body to act as a parasite that subtracts the nutrients needed to survive and grow.

Tumor characteristics

The key features of the tumors are:

Atypia of cells. Marked contrast to normal cells of the tissue in which it is implanted.
Continuous and indefinite growth of the tumor mass with a much faster pace.
Independence of the tumor in relation to our body.

Benign tumors

It is called benign tumor that:

  • It grows slowly with a rate much slower than the malignancy (cancer)
  • It develops in infiltrative rather expansive sense, ie as it grows crushes the surrounding healthy tissue without infiltrate or invade (as it does the malignancy)
  • No remote play. No metastases (ie, tumor affiliations distant organs or tissues of the primary tumor). Metastasis is typical malignant tumor.
  • No recurrence after surgical removal.
  • It commits the patient's general condition, ie, does not produce a severe state of malnutrition and general weakness typical of late-stage malignancies (cancerous cachexia).
  • Due to these characteristics, the benign tumor is always a local disease, whereas the malignant tumor is local to the first or initial stage and after generalizes. It is also a condition not always produce favorable because disorders involving the patient's life.

However, in some states and by the action of some influence, benign tumor may become malignant.

Types of benign tumors

Numerous varieties of benign tumors by being implanted in tissue and tumor cells that reproduce their structure. For example according to the tissue in which they are deployed are named: lipomas (fatty), fibroids (connective or fibrous), osteomas (bone), fibroids (muscular), neuromas (nerve), etc.

Malignant tumor 

Malignant tumor characteristics are:

  • It grows fairly quickly, usually faster than the benign tumor.
  • It is invasive or infiltrating. The tumor mass not compress the surrounding tissue but destroys inside the same by a series of long extensions.
  • Reproduced remotely (metastasis). Form tumors in organs that sits away from the original tumor. These metastases occur mainly in certain organs (lymph nodes, lungs, liver, etc..) And produced by atypical cells that shed from the original tumor mass reaches, through blood or lymphatic, the new body which causes the new cancer because they retain proliferative capacity.
  • Causes relapse easily. These recurrences occur even after extensive and careful surgery. Generally, recurrences are avoided in cases where the tumor is diagnosed and operates in very early stages when the tumor is localized and limited.
  • Compromise the patient's general condition. Failure to achieve adequate treatment or ineffective, the patient presents thins and an anemic state known as cachexia. Interestingly, it is not known whether this is caused by disorders caused by the mechanical presence of the tumor to cause organ dysfunctions, or toxic substances formed depends on the tumor, and spread throughout the body.
  • Originate anatomical and organ dysfunction. If a malignant tumor is implanted in the throat (laryngeal cancer) phonation is compromised, if it arises in the stomach mucosa compromise digestive function, and so on.
