The gland cancer can inherit?

Along with epidemiology research thorough,the tumor and the heredity related evidence are more and more many. The people discovered in some crowds and the family,has the so-called cancer family or some kind of cancer family gathers. Along with the tumor cell molecular biology research progress,confirmed gradually the existence has one kind of cancer tendentiousness in these family member ── to damp the cancer gene heterozygosity loss. This kind of phenomenon causes these specific crowds organism cell to have easily and presses the cancer factor compared to other people in the carcinogenic factor under the multiple actions to have the canceration.

Breast cancer has certain family heredity tendency. Breast cancer in certain family's accumulation phenomenon,is taken bad the risk in the level relative to reach as high as 50%,in the family the far relative is taken bad the risk to be small. The epidemiology investigation discovered that,breast cancer patient's level relative and the common crowd compare,contract breast cancer the risk to increase 2~3 times; Has the woman in his/her mother and the sisters who a person contracts breast cancer,the risk which the trouble should get sick is higher.This kind of heredity tendency also displays: The two-sided breast cancer patient is higher than the single side breast cancer patient's relative disease incidence rate. In front of the menopause contracts breast cancer,patient's level relative is taken bad the risk to increase 9 times; Menopause future trouble breast cancer,patient's level relative is taken bad the risk to increase 4 times. The age analysis is taken bad which from breast cancer patient,the age is more young,the relative contracts the cancer the risk to be bigger; Exhausts oneself the crowd are more,relative's risk is bigger.

Although has made the very big progress at present to the heredity gene research,but more research indicated the tumor is more than one kind of reasons,the multi-stages and change suddenly many times result multi-factor disease,is not at all merely some sole intrinsic factor (for example heredity gene flaw and so on) or the sole external factor (for example carcinogenic environment and so on) alone causes,but is many kinds of factors takes turn,correlation result. Must say the heredity factor and the carcinogenic factor,pressed the cancer factor the multiple actions only then finally to form the canceration.

In brief,breast cancer family gathers the tendency,possible and the heredity factor and the environmental factor all concern,all cannot explain breast cancer completely with the sole heredity factor or the environmental factor in family's accumulation tendency. But to has the woman in the level relative who contracts breast cancer,the regular breast inspection is necessary and safe. (womimi.net)
