The breast cancer studies recent discovery

Discovers one: Cancer stem cellThe US University of Michigan's scientist newest researchdemonstration, in the human body breast cancer cell only has extremelylittle partially has forms the malignant tumor the ability in, is thebreast cancer organizes "the stem cell". This kind "the stem cell" hasthe self- duplication ability, may form the breast cancer to organizeeach kind of other types cell, this meant it once proliferates, hasthe possibility to form the new breast cancer organization in otherspots. The scientist has altogether selected 9 breast cancer patients'home position or the shift tumor organization takes the sample, andcarries on the classification based on the cell membrane surfaceprotein characteristic to tumor cell, then separately pours into thedifferent type tumor cell experimental mouse in vivo. The resultdiscovered that, in the tumor organization has "the stem cell" thequantity not to be many, actually can cause experimental mouse invivo to form the new tumor, moreover the new tumor also may separate"the stem cell" similar, they also have continue to form the tumor theability. The research discovered, experimental mouse in vivo so longas has 100 ~ 200 this kinds "the stem cell" to be able to have thetumor, compares with it, the human body breast cancer organizes othertypes cells even if quantity up to ten thousand, pours intoexperimental mouse in vivo not to be able to initiate the tumor. Thehumanity if can develop the new medicine, thoroughly eliminates thebreast cancer to organize most dangerous "the stem cell", can achievethe twice the result with half the effort effect.Discovers two: The movement reduces suffers from the trouble riskSome research believed that, must want to cause to contract thebreast cancer the danger remarkably to reduce, maintains the highermovement level to be extremely essential. The New York StateUniversity's researchers have carried on the investigation to 1,550 40~ 85 year old women, starts the time which exercises respectively isbefore when 16 years old and the research starts 20 year, 10 year, 2years, the exercise standard is can cause its perspiration. Afterresult these frequently participate in the exercise 绝经 the woman(average each week to 2 hours) not to contract the breast cancer therisk to be lower. Before two groups of investigations objects, theresearch starts in for 20 years the most active these women,participation exercise time each week surpasses for 3 half hour,contracts the breast cancer the possibility to compare the movementwoman not to be few one half. Persisted participates in the exercise,like takes a walk, rides the bicycle, makes the gymnastic exercisesand so on, all can cause to contract the breast cancer the danger toreduce.Discovers three: The gene examination may forecast the condition"Lance" the magazine recent publication article indicated that,surveys in the breast cancer cell gene activeness, may forecast breastcancer progress degree how, for example is whether easy to proliferateto other organs, is easy to enter as well as is whether easyto recur and so on. The researcher carries on the gene examination to89 breast cancer women, examines 50 ~ 100 to have the similarcharacteristic gene group, finally demonstrated the breast cancer theprogress degree and the gene group's pattern concerns. Therefore, evenif on clinical not yet discovered has the lymph node the shift and soon the fast progress to draft unfolds, if the gene examination promptsit to have the progress to be possible, also should enhance vigilantlyto this kind of patient, takes the corresponding remedial measure.Discovers four: The contraceptive has nothing to do with with thebreast cancerThe American disease control and the prevention centerresearcher carries on the investigation after 35 ~ 64 year old ofbetween 9,200 American woman to point out that, the use oralcontraceptive cannot increase the woman to suffer from contracts thebreast cancer the risk. Their investigation discovered that, thesenever have used the oral contraceptive woman, it contracted the breastcancer the risk or uses the oral contraceptive woman with these not todistinguish; Moreover said to the oral contraceptive user that, whenstarts with the medicine, in the medicine to contain estrin how manyand so on, also with contracts the breast cancer to have nothing to dowith.Discovers five: Weight gain and waist buttocks big dangerCarries on when the human body data survey to 1,233 breastcancer women and 1,237 collators discovered according to the Canadianresearcher that, adult time weight gain and the waist buttocks ratiois two danger signals which the breast cancer occurs. The researcherdiscovered that, the waist is bigger than 868 centimeters ratios to besmaller than 715 centimeters to have the breast cancer risk toincrease 30%; But the waist buttocks ratio in 081 above ratios issmaller than 072, the breast cancer risk increases 43%; After increases the weight 22 kilograms compared to increase is short againto 772 kilograms, the risk increases above 35%. When, is pregnant theweight gain surpasses 172 kilograms women to compare the weight gainfew easily breast cancer
