Still Smoking?? These Facts Will Definitely Blow You Off

How Is Smoking Related to Cancer?
Smoking can cause cancer and then block your body from fighting it:
·         Poisons in cigarette smoke can weaken the body’s immune system, making it harder to kill cancer cells. When this happens, cancer cells keep growing without being stopped.
·         Poisons in tobacco smoke can damage or change a cell's DNA. DNA is the cell's "instruction manual" that controls a cell's normal growth and function. When DNA is damaged, a cell can begin growing out of control and create a cancer tumor.
Doctors have known for years that smoking causes most lung cancer. It's still true today, when nearly 9 out of 10 lung cancers are caused by smoking cigarettes. In fact, smokers have a greater risk for lung cancer today than they did in 1964, even though they smoke fewer cigarettes. One reason may be changes in how cigarettes are made and what they contain.5
Treatments are getting better for lung cancer, but it still kills more men and women than any other type of cancer. More than 7,300 nonsmokers die each year from lung cancer caused by secondhand smoke.
Smoking can cause cancer almost anywhere in your body, including the.
·         Blood (acute myeloid leukemia)
·         Bladder
·         Cervix
·         Colon and rectum
·         Esophagus
·         Kidneys and ureters
·         Larynx
·         Liver
·         Lungs
·         Mouth, nose, and throat
·         Pancreas
·         Stomach
·         Trachea
Men with prostate cancer who smoke may be more likely to die from these diseases than nonsmokers.
Smokeless tobacco also causes cancer, including cancers of the:
·         Esophagus
·         Mouth and throat
·         Pancreas
How Can Smoking-Related Cancers Be Prevented?
Quitting smoking lowers the risks for cancers of the lung, mouth, throat, esophagus, and larynx.
·         Within 5 years of quitting, your chance of cancer of the mouth, throat, esophagus, and bladder is cut in half.
·         Ten years after you quit smoking, your risk of dying from lung cancer drops by half.
If nobody smoked, one of every three cancer deaths in the United States would not happen.

Tarvelling Frequently by Air? Here Are Tips To Keep Ears Safe.

Ear problems are the most common medical complaint of airplane travelers, and while they are usually simple, minor annoyances, they may result in temporary pain and hearing loss. Make air travel comfortable by learning how to equalize the pressure in the ears instead of suffering from an uncomfortable feeling of fullness or pressure. 
WHY DO EARS POP?
Normally, swallowing causes a little click or popping sound in the ear. This occurs because a small bubble of air has entered the middle ear, up from the back of the nose. It passes through the Eustachian tube, a membrane-lined tube about the size of a pencil lead that connects the back of the nose with the middle ear. The air in the middle ear is constantly being absorbed by its membranous lining and re-supplied through the Eustachian tube. In this manner, air pressure on both sides of the eardrum stays about equal. If, and when, the air pressure is not equal the ear feels blocked.
The Eustachian tube can be blocked, or obstructed, for a variety of reasons. When that occurs, the middle ear pressure cannot be equalized. The air already there is absorbed and a vacuum occurs, sucking the eardrum inward and stretching it. Such an eardrum cannot vibrate naturally, so sounds are muffled or blocked, and the stretching can be painful. If the tube remains blocked, fluid (like blood serum) will seep into the area from the membranes in an attempt to overcome the vacuum. This is called “fluid in the ear,” serous otitis or aero-otitis. Uncommon problems include developing a hole in the ear drum, hearing loss and dizziness.
 
The most common cause for a blocked Eustachian tube is the common cold. Sinus infections and nasal allergies are also common causes. A stuffy nose leads to stuffy ears because the swollen membranes block the opening of the Eustachian tube.
HOW CAN AIR TRAVEL CAUSE HEARING PROBLEMS?
Air travel is sometimes associated with rapid changes in air pressure. To maintain comfort, the Eustachian tube must open frequently and wide enough to equalize the changes in pressure. This is especially true when the airplane is landing, going from low atmospheric pressure down closer to earth where the air pressure is higher.
Actually, any situation in which rapid altitude or pressure changes occur creates the problem. It may be experienced when riding in elevators or when diving to the bottom of a swimming pool. Deep sea divers, as well as pilots, are taught how to equalize their ear pressure. Anybody can learn the trick too.
HOW TO UNBLOCK EARS?
Swallowing activates the muscles that open the Eustachian tube. Swallowing occurs more often when chewing gum or when sucking on hard candies. These are good air travel practices, especially just before take-off and during descent. Yawning is even better. Avoid sleeping during descent because swallowing may not occur often enough to keep up with the pressure changes.
 
During decent, if yawning and swallowing are not effective, pinch the nostrils shut, take a mouthful of air, and direct the air into the back of the nose as if trying to blow the nose gently, you should feel a pressure buildup but do not let the air out your mouth The ears have been successfully unblocked when a pop is heard. This may have to be repeated several times during descent.
Even after landing, continue the pressure equalizing techniques and the use of decongestants and nasal sprays. If the ears fail to open or if pain persists, seek the help of a physician who has experience in the care of ear disorders. The ear specialist may need to release the pressure or fluid with a small incision in the ear drum.
For some people, these techniques may not work.  If you fly frequently and have chronic issues with pressure or pain, you doctor may recommend placing small pressure equalization tubes.
HOW TO HELP BABIES UNBLOCK THEIR EARS?
Babies cannot intentionally pop their ears, but popping may occur if they are sucking on a bottle or pacifier. Feed the baby during the flight, and do not allow him or her to sleep during descent. Children are especially vulnerable to blockages because their Eustachian tubes are narrower than in adults. 
IS THE USE OF DECONGESTANTS AND NOSE SPRAYS RECOMMENDED?
Many experienced air travelers use a decongestant pill or an over the counter nasal spray an hour or so before descent. This will shrink the membranes and help the ears pop more easily. Travelers with allergy problems should take their medication at the beginning of the flight for the same reason. However, avoid making a habit of over the counter nasal sprays. After a few days, they may cause more congestion than relief.
Decongestant tablets and sprays can be purchased without a prescription. However, they should be avoided by people with heart disease, high blood pressure, irregular heart rhythms, thyroid disease, or excessive nervousness. Such people should consult their physicians before using these medicines. Pregnant women should likewise consult their physicians first.
Tips to prevent discomfort during air travel
  • Consult with your surgeon on how soon after ear surgery it is safe to fly.
  • •Postpone an airplane trip if a cold, sinus infection, or an allergy attack is present.
  • •Patients in good health can take a decongestant pill or nose spray approximately an hour before descent to help the ears pop more easily.
  • •Avoid sleeping during descent.
  • •Chew gum or suck on a hard candy just before take-off and during descent.
  • •When inflating the ears, do not use excessive force. The proper technique involves only pressure created by the cheek and throat muscles.
  • •These tips may also be used for people who scuba dive.

What is Sinusitis?

Sinusitis means your sinuses are inflamed. The cause can be an infection or another problem. Your sinuses are hollow air spaces within the bones surrounding the nose. They produce mucus, which drains into the nose. 
If your nose is swollen, this can block the sinuses and cause pain.
There are several types of sinusitis, including
  • Acute, which lasts up to 4 weeks
  • Subacute, which lasts 4 to 12 weeks
  • Chronic, which lasts more than 12 weeks and can continue for months or even years
  • Recurrent, with several attacks within a year
Acute sinusitis often starts as a cold, which then turns into a bacterial infection. 
Allergies, nasal problems, and certain diseases can also cause acute and chronic sinusitis.
Symptoms of sinusitis can include fever, weakness, fatigue, cough, and congestion. 
There may also be mucus drainage in the back of the throat, called postnasal drip. Your health care professional diagnoses sinusitis based on your symptoms and an examination of your nose and face. You may also need imaging tests.
 Treatments include antibiotics, decongestants, and pain relievers. Using heat pads on the inflamed area, saline nasal sprays, and vaporizers can also help.

What is lung Cancer?

LUNG CANCER 

Note: All cancers and patients are highly individual, so treatment will be tailored to their specific cases. Some information may become outdated, as new or better regimens are always being
researched/tested/approved. Not all chemotherapy agents are available in all countries. 


Suggestions for information to be included or needed changes in this overview are always welcome!

Excerpted from M.D. Anderson's adaptation of NCI's "What You Need to Know About Lung Cancer"

What are the symptoms of lung cancer?
Common signs and symptoms of lung cancer include:
• A cough that doesn’t go away and gets worse over time
• Constant chest pain
• Coughing up blood
• Shortness of breath, wheezing, or hoarseness
• Repeated problems with pneumonia or bronchitis
• Swelling of the neck and face
• Loss of appetite or weight loss
• Fatigue
These symptoms may be caused by esophageal cancer or by other conditions.

How is lung cancer diagnosed?
If any of the above symptoms do occur, your doctor will evaluate your medical history, smoking history, exposure to environmental and occupational hazards, and family history of cancer. The doctor will also perform a physical exam and may order a chest x-ray and other diagnostic tests. If lung cancer is thought to be present, a sputum cytology test will be ordered to exam your mucous cells under a microscope. To confirm the presence of lung cancer, the doctor will perform a biopsy—the removal of a small sample of tissue from the lung for examination under a microscope. A number of procedures may be used to obtain this tissue such as a bronchoscope, needle aspiration, thoracentesis, or thoracotomy.

What is staging?
If the diagnosis is lung cancer, your doctor will need to know the stage (or extent) of the disease. Staging is a way to find how far the cancer has spread and to which parts of the body. Lung cancer often spreads to the brain and bones. Once your doctor knows what stage your cancer is, he or she can plan your treatment. Some tests used to determine if the cancer has spread include CAT/CT scan (computerized tomography), PET scan (Positron emission tomography), MRI (magnetic resonance imaging), radionuclide scanning, bone scan, and/or mediastinoscopy/mediastinotomy.

How is lung cancer treated?
The treatment of lung cancer depends on a number of factors, including the type of lung cancer (NSCLC or SCLC); the size, location, extent of the tumor; and the general health of the patient. Many different treatments and combinations of treatments may be used to control lung cancer, and/or to improve quality of life by reducing symptoms. Treatments for lung cancer include surgery, radiation therapy, chemotherapy, and photodynamic therapy. Clinical trials are also a treatment option.

How is non–small cell lung cancer treated?
Patients with non-small cell lung cancer may be treated in several ways. The choice of treatment depends mainly on the size, location, and extent of the tumor. Surgery is the most common way to treat this type of lung cancer. Cryosurgery, a treatment that freezes and destroys cancer tissue, may be used to control symptoms in the later stages of non-small cell lung cancer. Radiation therapy and chemotherapy may also be used to slow the progress of the disease and to manage symptoms.

How is small cell lung cancer treated?
Small cell lung cancer spreads quickly. In many cases, cancer cells have already spread to other parts of the body when the disease is diagnosed. In order to reach cancer cells throughout the body, doctors almost always use chemotherapy. Treatment may also include radiation therapy aimed at the tumor in the lung or tumors in other parts of the body (such as in the brain). Some patients have radiation therapy to the brain even though no cancer is found there. This treatment, called prophylactic cranial irradiation (PCI), is give to prevent tumors from forming in the brain. Surgery is part of the treatment plan for a small number of patients with small cell lung cancer.

Do You Have lung Cancer?

If you are writing to say that you are worried because you have symptoms related to Lung Cancer but you haven't been to a doctor yet, here is a summary of what we are probably going to say to you:

* Don't panic!
* Consulting Google will only increase your fears.

Dr. Google can convince people that they are seriously ill when mostly they are not.

* You probably don't have Lung Cancer. There are many things that can cause symptoms similar to LC but most are not, in fact, LC!

* Unfortunately, we cannot tell you that you definitely do NOT have LC either. We are not doctors, and the ONLY way that LC can be diagnosed is with a biopsy. What we can tell you is that you are obviously concerned, so you should seek medical counsel for your own peace of mind. 

* In summary, if you are concerned, go see a doctor. If you are not satisfied with how they treat you, see another one. You are the greatest advocate for your own health, as you have the greatest stake in it.

* If you have been to a doctor who suspects Lung Cancer, or you are currently undergoing tests specifically for Lung Cancer, we will support you through diagnosis. You are free to post in this area of the Forum. However, if a doctor tells you that you do NOT have LC, please refrain from posting your fears on this site as there is nothing else we can do to help you. This has proven to be upsetting to our members who are currently battling LC or have loved ones who are.

If you have any questions about whether or not you should post, please feel free to send me a private message and I will let you know. Best of luck!
