PASSIVE SMOKING

Passive smoking is the inhalation of smoke which escapes directly into the air from a lit cigarette.
It results from just being in the presence of a smoker.

Non-smokers are exposed to second-hand smoke, which is the unfiltered smoke that rises from the burning cigarette and which also includes the smoke exhaled by the smoker.

Second-hand smoke contains most of the toxic components of mainstream smoke.
Health Risks From Passive Smoking


Babies of smoking mothers weigh less than those of non-smoking mothers.
Higher rates of miscarriage have been observed in women who smoke.
Higher rates of neonatal deaths, as well as sudden infant death syndrome, have been reported.
Children of smoking parents have higher rates of pneumonia, bronchitis, and other respiratory symptoms, and for developing lung cancer later in life.
Non-smoking adults also experience conditions resulting from passive inhalation.

Effects include:

    eye, nose, throat irritation
    headaches, dizziness and nausea
    aggravation of allergies and asthma
    impairment of lung function

The risk of lung cancer

LUNG CANCER

  

The Lungs

The lungs are a pair of cone-shaped organs that are situated inside the chest. The lungs bring oxygen into the body and take out carbon dioxide, which is a waste product of the cells of the body.

Tubes called bronchi make up the inside of the lungs.

Your lungs have an extensive network of blood and lymph vessels. Cancer cells may grow into these vessels and be carried by the blood or lymph and be deposited elsewhere in the body.

Cancer can spread from the lungs to almost any site in the body. Most commonly it spreads to the brain, bone, bone marrow and liver. Lung cancer takes many years to develop. It is the second most common cancer in women.

There are two basic types of lung cancer - small cell and non-small cell cancer. These different types grow and spread in different ways. Small cell lung cancer is a disease in which cancer cells are found in the tissues of the lungs. It is usually found in people who smoke or who used to smoke cigarettes.

The non-small cell type of lung cancer is a common disease and is usually associated with people who used to smoke, passive smoking and radon (a radioactive gas) exposure.

SIGNS AND SYMPTOMS

These can include:

- hoarseness - persistent cough - blood in your phlegm - shortness of breath

- chest pain - loss of appetite - difficulty in swallowing - weakness - paleness

- high temperature - joint swelling - bone pain or tenderness - weight loss

Smoking causes about 85% of lung cancer cases. Cigarette smoke contains over 4,000 different chemicals, many of which are proven carcinogens (materials that are known to cause cancer). Lung cancer occurs most in people over 50 who have a long history of cigarette smoking.

RISK FACTORS

The risk of lung cancer increases, the more cigarettes smoked per day.

Also, the earlier the age at which smoking began, the greater the risk of lung cancer.

Passive smoking is also known to increase the risk.

In rare cases, exposure to certain industrial substances, such as arsenic, certain organic chemicals and asbestos.

Radiation exposure from occupational, medical and environmental sources.

EXAMINATIONS

If the patient has a persistent cough that produces phlegm, the phlegm will be examined for cancer cells.

The doctor may order a chest X-ray or a specialised X-ray such as the CAT scan, which helps to locate any abnormal spots in the lungs. A bronchoscopy may be performed. A bronchoscope is a small tube inserted through the nose or mouth, down the throat, into the bronchial tubes. During this examination, the doctor may also obtain a biopsy or other sample of lung tissue to test for cancer cells. Pressure is felt during the examination but very seldom pain.

TREATMENT

Surgery may cure lung cancer. It is used in early stages of the disease.

Radiation therapy can also be used.

This is used:

in a combination with chemotherapy and sometimes with surgery to offer relief from pain.

Chemotherapy may be used: in a combination with chemotherapy and sometimes with surgery to offer relief from pain.

along with surgery.

in more advanced stages of the cancer.

in all the stages of small cell cancer.

PREVENTION :

STOP SMOKING

Try to avoid second-hand smoke/passive smoking.

Ask questions about your work environment if you are exposed to industrial dusts and fumes, as it can be very dangerous.

New Ways to Diagnose Colon Cancer

New advances in colonoscopy promise faster and easier screenings.

Looking to the Future continued...

Macari says that in order to avoid dual prep times some medical centers are coordinating the virtual colonoscopy with a gastroenterologist who is standing by.

"In the event the virtual colonoscopy reveals a problem, the gastroenterlogist is right there ready to perform a standard colonoscopy without the need for a second prep," says Macari.

This dual-system screening is currently being performed in a select number of major medical centers nationwide.

The Virtual Test

While looking towards the future is promising, there is also one futuristic method of colon screening that is available right now. It's called a "Virtual Colonoscopy" -- a noninvasive screening that uses X-ray beams to look inside the colon.

Doctors say there is so little fuss and bother, the whole procedure is over in less than 10 minutes.

"For the most part, when a patient leaves here they are pleased and happy. They are on and off the table in no time, and there is no sedation. You can literally go back to work in 10 minutes," says Michael Macari, director of abdominal imaging at NYU Medical Center in New York City.

Besides the fact that the screening is noninvasive, Marcari says that prior to the test his center also uses carbon dioxide -- compared with "room air" -- to extend the colon. The difference, he says, means very little cramping and almost no residual pain after the screening is completed.

"Initially there is a little pressure but the carbon dioxide gets absorbed so fast, by the time they leave they feel fine," says Macari.

Looking to the Future

While the screening itself may be fast and easy, right now it requires the same preparation as the regular colonoscopy, so patients are not spared the pretesting discomfort.

However, Macari reports that may change in the not-too-distant future, with the advent of a process called "fecal tagging."

In this procedure, he says, patients drink an agent which -- once inside the colon -- latches onto the fecal material and helps doctors differentiate between that and polyps on the scan.

"We just completed study of 80 patients using fecal tagging and no bowel cleansing and we had a very high rate of detection of polyps over 10 millimeters, which many believe is the real threshold for removal," says Macari.

In another study published in the journal Radiology doctors from Belgium compared fecal tagging with standard colonoscopy preparation. They found that fecal tagging left behind more fecal residue, but improved differentiation of polyps. The fecal tagging also dramatically reduced patient discomfort, side effects, and sleep disturbances.

Still, Marcari says he would not routinely recommend it for virtual colonoscopy -- at least not until larger studies are done.

"Right now it's used if a patient simply cannot tolerate the standard prep, or if a medical condition precludes them from participating in the standard prep," says Macaria.

As easy as a virtual colonoscopy appears to be, Brooks cautions that should a polyp be found during the exam, the patient must still undergo a standard colonoscopy to have the growth removed.

"This requires a second prep and a second procedure whereby if you have the standard colonoscopy screening and something is found, it can be removed on the spot without the need for a second procedure," he says.

Understanding Colorectal Cancer - Symptoms

What Are the Symptoms of Colorectal Cancer?

In its early stage, colorectal cancer usually produces no symptoms. The most likely warning signs include:

• Changes in bowel movements, including persistent constipation or diarrhea, a feeling of not being able to empty the bowel completely, or rectal bleeding
• Dark patches of blood in or on stool; or long, thin, "pencil stools"
• Abdominal discomfort or bloating
• Unexplained fatigue, or loss of appetite or weight

Call Your Doctor About Colorectal Cancer If:

• You notice a change in your bowel movements, experience bleeding from the rectum, or notice blood in or on your stool. Don't assume you have hemorrhoids; your doctor will most likely perform a rectal examination and possibly a sigmoidoscopy or schedule a colonoscopy -- an examination that involves a long flexible tube inserted in your rectum.
• You experience persistent abdominal pain, unusual weight loss, or fatigue. These symptoms may be due to other causes, but they could also be linked to cancer.
• You are diagnosed with anemia. In determining its cause, your doctor should check for bleeding from the digestive tract because of colorectal cancer.

Myth: Tanning Can Hide Cellulite

Tanning may make the cellulite less obvious, but when the tan fades, the cellulite might look even worse. That’s because frequent exposure to UV rays can damage the skin, making it thinner and less resilient, according to the International Academy of Cosmetic Dermatology.

Risk Factors You Can Control

Although you can’t completely prevent cellulite, your lifestyle choices may affect its appearance. Factors that worsen the condition include:

• Yo-yo dieting
• An excessively high-carbohydrate diet
• An increase in total body fat
• Being inactive
• Fluid retention or being dehydrated

Risk Factors You Can't Control

Genetics is destiny when it comes to cellulite. If your mother has cellulite, you probably will, too. White women are more likely to have cellulite than Asian women. Other risk factors include:

• Hormonal changes in pregnancy
• Aging

Myth: Skinny People Don’t Have Cellulite

Cellulite is related to the structures within the skin, so even slender women are likely to have some cellulite. And if thin skin runs in your family, the cellulite you have will be more visible.

Causes of Cellulite

Cellulite is caused by fat deposits that sit side-by-side with tough collagen fibers that are anchored to the muscle beneath. When the fibers pull tight, or the fatty areas grow larger, the fat deposits may bulge out. Cellulite is much more common in women than in men.

Signs of Cellulite

Cellulite is purely a cosmetic problem, not an illness or medical

condition. It can look like faint dimples or an "orange peel" texture,

and may only be seen when the skin is pressed. But for some people

cellulite can be very conspicuous, forming large areas of lumpy skin,

deep dimples, and creases.  While it's most common on the thighs and

backside, it occurs on the abdomen, upper arms, and breasts, too.

What Is Cellulite?

Cellulite is the rippled appearance of skin, usually on the thighs and buttocks of women, that's caused by the underlying layer of fat. Paparazzi sometimes zoom in on Hollywood stars in bikinis to show the puckering in their skin. It doesn't mean the stars gained weight or failed to work out. The ugly truth: Almost every woman will eventually develop cellulite.
