Skin Cancer!!!

June 28th, 2008

There are several types of skin cancer, most of which are associated with prolonged exposure to sunlight. Fair-skinned people are most at risk. Exposure to the sun is a risk factor and should be avoided from babyhood; the use of sun beds is also a risk factor and .should likewise be avoided. Skin cancer is now the most common form of cancer in the world. In recent years, the incidence around the world has escalated, and the condition now affects millions of people worldwide. The good news is that skin cancer can usually be cured if it is diagnosed early, though preventive measures are always preferable.

WHAT ARE THE RISKS?
The usual cause of skin cancer is prolonged exposure to the harmful ultraviolet radiation in sunlight. The risk is higher if you are fair-skinned and if you live or take holidays in areas with intense sun; the closer you are to the equator, the greater the risk. It’s the cumulative hours of sunshine that count so if you live in a very sunny place you’ll reach your “cancer-inducing dose” earlier than somewhere like the UK where there isn’t so much sun. The recent depletion of the ozone layer is thought to have played a part in increasing the incidence of skin cancer because the ozone layer acts as a shield against harmful ultraviolet (UV) light. Sun beds, which give out ultraviolet light, may also cause skin cancer. You should also bear in mind that the more times you have been sunburned, the greater your chance of developing malignant melanoma, the most dangerous form of skin cancer.

If you work outside or have been sunburned (particularly in childhood), you could be vulnerable to skin cancer. People who have fair skin are especially susceptible because they have low levels of melanin, the pigment that give the skin its colour and helps protect it from the sun’s harmful ultraviolet rays.

To reduce the risk of developing skin cancer, try to avoid exposure to the sun and protect your skin when outside. Examine your skin regularly, and ask someone else to check your back and scalp. Wear UV-resistant clothing in areas of intense sunshine and where there’s a lot of reflection, for example on snow or water.

Real Weight Loss!!!

June 20th, 2008

The secret to losing weight is this: Burn more calories than you eat. When the body uses more energy than it takes in (food equals energy). It depletes its fat stores. In other words, eat less and you body will burn fat for energy. Of course, what you eat is important, too. A diet based solely on cabbage soup won’t provide the nutrition your body needs-and you will get tired of it soon enough and return to your old eating habits with a vengeance.

Any weight-loss plan needs to center on foods you can keep eating for a lifetime—and of course it helps if those foods will also help protect you from cancer and other diseases. After all, it’s not all about losing weight. A diet that is high in meat and low in fruits may lead to short-term weight loss, but is not in keeping with current nutritional knowledge. Excessive meat consumption has been linked with a variety of diseases and a high fruit diet protect against cancer.

When people want to lose weight, they usually want fast results. Most people who go on crash diets to shed heft fast usually end up putting it back on just as quickly – and often put back more then they lost. Experts suggest a goal of losing about 1lb (0.45 kg) a week. There are 3500 calories in 1 lb (0.45 kg) of stored fat, so you will have to reduce your food intake by 500 calories a day to get there. Or you can eat 250 fewer calories and burn 250 more through exercise.

Research shows that people who exercise in addition to eating less keep off the most weight for the longest time. Work up to getting as least 30 minutes of moderate exercise (such as fast-paced walking) a day. By exercising you will raise your metabolism so that you burn more calories, even as you sleep. Exercise also helps you feel better mentally and physically, and may help you stick to your weight-loss plans.

Causes and Risk factors of Diabetes!!!

June 12th, 2008

Genes play a part in both types of diabetes mellitus, but environmental factors are thought to be triggers. Of the people who inherit the genes for type 1 diabetes, only a small proportion actually develop the condition. Many people newly diagnosed with type 1 diabetes have antibodies to a protein found in cow’s milk, leading some researchers to suggest that feeding babies with formula milk may trigger the immune system to destroy pancreatic cells. It is more commonly thought that types 1 diabetes occurs as a result of a viral infection that damages the pancreas.

Type 2 is by far the most common form of diabetes mellitus. Risk factors include a family history of diabetes, increasing age and being of Asian or Afro-Caribbean origin. Being overweight, particularly if you store fat around the waist, is another risk factor as obesity is known to increase insulin resistance. Weight loss and keeping active reduce insulin resistance.

Globally, the number of people who have this form of diabetes is rising. This is attributed to the fact that people in the developed world are increasingly inactive and overweight.
