Using many drugs to inhibit calcium absorption is easy for breast cancer

A new study shows that long-term use of calcium absorption blockers (Calcium channel blockers), a drug used to treat high blood pressure, can double the risk of breast cancer in women. .

Research results of scientists from Fred Hutchinson Cancer Research Center (USA), announced on August 6, that women aged 55-74, regularly using calcium inhibitors In order to prevent heart attacks and strokes for 10 years or more, there is a double risk of breast cancer compared to those who do not use or use other antihypertensive drugs.

Dr. Christopher Li, head of the expert team, said this is the first study of the link between the long-term use of the drug and breast cancer.

The study was conducted through the investigation of drug use by nearly 1,800 women before and after the two most common types of breast cancer in the period 2000-2008.

Kathleen Malone, co-author of the study, said the results of this study are not intended to prevent all women from using prescription drugs that are prescribed, but simply to warn people to consider when using medicine.

Ms. Malone explained that calcium inhibitors are one of the relatively new drugs, so very few women use the drug for 10 years or more, the minimum time to increase the risk of breast cancer. . Meanwhile, this drug is still used to effectively treat hypertension.

During the study, experts also determined that other antihypertensive drugs, such as ACE inhibitors (ACE) , beta-blockers and diuretics are completely unrelated. risk of breast cancer. Even ACE inhibitors can reduce the risk of developing breast cancer.
