Blockage in heart is a common term used for narrowing of coronary arteries. Coronary arteries are vessels, which supply blood and thus oxygen and food to continuously working heart muscles. Heart muscles, which are not tired working from the birth till death, however, cannot sustain long without blood supply.
A reduction in blood supply gives rise to ischemia of heart muscles commonly manifested as chest discomfort or angina. A sudden complete shutdown of blood supply leads to heart attack leading to permanent damage to heart (if blood flow not reestablished promptly).
But what causes these arteries to block? Sedentry lifestyle is the most primary reason of these blockages. Cigarette smoke increases the rate of atherosclerosis in the arteries of the heart, legs, and the aorta -- the largest artery in the body. Also, there is an increase in the risk of heart attack if a first-degree relative (parent or sibling) has had a heart attack or stroke. That is mainly seen when the relative has had a heart attack before the age of 45 if they are male, 55 if they are female.
High levels of ''bad'' cholesterol, or low-density lipoprotein (LDL), are also the major contributors to arterial plaque formation. Having high blood pressure also increases the rate at which arterial plaque builds up. It also hastens the hardening of clogged arteries. LDL a normal component of blood (upto certain limit) starts depositing in arteries as early as 10 years of age!
Deposition of billions of LDL molecules over several years on inner surface of arteries gives rise to visible narrowings in these arteries. Flow ahead of these narrowings is reduced in proportion to the narrowing. At a level of 70 % narrowing the flow is reduced to give ischemia (and angina) during exercise. Gradually increasing degree of narrowing reduces the exercise needed for ischemia and angina; a narrowing of more than 90 % can give symptoms at rest. A sudden clot formation at any of these stages can block the flow suddenly giving a heart attack.
If LDL is a normal component of blood, why it is deposited in the arteries at first place?
LDL above a certain limit in blood starts depositing in the arteries. Diabetes, Hypertension, smoking, less exercise and genetics makes it more sticky thus making narrowing faster. This is why these risk elements need to be properly attended for prevention from heart disease. For treatment medicines are important for stopping the progression of narrowings; angioplasty is a method of fast resolution of blockage; and bypass surgery is the method of creating a whole new blood supply for the affected part of the heart. If you wish to discuss about any specific problem, you can consult a Cardiologist.
Breast Cancer is a type of cancer which develops in the cells of the breasts. It is second most common form of cancer after skin cancer, among women in the United States of America. As there has been an increase in the support for breast cancer awareness and proper funding for research has helped to make advancement in the diagnosis of the disease and also in the treatment options. As people and doctors have become more aware of what leads to breast cancer, the precautions which women should consider taking so that they can prevent themselves from getting affected by the diseases and the types of treatment to be followed by the doctors, so that they can put women on the path to recovery, the deaths associated with the disease have come down.
So, even if somebody is diagnosed with cancer, their chances of survival are extremely high nowadays. Before going into the causes of breast cancer, let’s take a look at some of the symptoms which act as indications to suggest that there is a possibility of women getting affected by breast cancer.
Causes
Medical science, technology has advanced to a great extent and there has been campaigns on breast cancer awareness. Despite all the progress, still doctors are not clear as to why do cancerous cells in the breast begin to multiply at abnormal rates from time to time. There are certain factors due to which this happens. Let’s discuss in detail:
- Age: Age is a big factor behind breast cancer. As women grow older, chances of them becoming prone to developing cancerous cells in the breasts grow. Unfortunately, age is something beyond anyone’s control.
- Medical history: Medical history plays a big role in breast cancer occurring in women. If a woman has had cancer in one breast, chances are high that she would develop cancerous cells in her other breast as well.
- Family history: Another big factor behind a woman getting plagued by the dreadful disease of breast cancer, is the history of her mother, sister or daughter have already been engulfed by the disease.
- Being exposed to radiation: Exposing yourself to radiation treatments would always increase the chances of getting affected by breast cancer.
- Obesity: Being overweight is never a good thing. A whole lot of problems occur due to this, cancer being one of them.
