Prevention
of Lung Cancer when You are at Risk,
or when You Already Have Lung Cancer
(April 27th, 2009)
As
the old adage goes, prevention is
better than cure! In this topic, we
will explore the types of things you
should do to prevent or avoid developing
lung cancer if you don't already have
it. If you do already have it, we
will discuss how to minimize the symptoms,
live a better life and steps to better
pain management. Some reasons why
patients could potentially develop
lung cancer include exposure to Asbestos
or Radon, smoking cigarettes or tobacco
related products, second-hand smoke,
or if your family member has lung
cancer and you are close to that person
or through other environmental factors.
If your doctor has said you are at
risk of developing lung cancer, the
first logical step would be to stop
smoking if you already do. This is
because smoking causes not only lung
cancer but also Cancer of the Esophagus,
bladder, larynx, pancreas, etc. Quitting
smoking has many benefits including
more lung capacity, free flow of blood
from the lungs to other essential
organs of the body, lower blood pressure
and more. Although easier said than
done, we realize it is difficult to
quit smoking in an instance or a matter
of months. However, with tools such
as gum or nicotine patches and behavioural
patterns & lifestyles, this addiction
can be lost. If you would like to

Screening Lung Cancer
& Early Detection Methods
The purpose of screening
lung cancer programs is to detect
lung cancer at early stages when the
symptoms are less, and it has not
spread very further in to other organs.
Treatments conducted during early
stages of lung cancer are less invasive
surgically, have a higher survival
rate and more successful treatment
varieties are available. In a recent
statistic, the number of people who
had a good 5 year survival rate for
their lung cancers that had not localized
(had not spread far) was almost 50%.
This percent drops to 2% for those
people whose lung cancers had metastized
(spread far beyond the lungs). Early
detection therefore helps saves lives,
however currently there is no approved
screening test that for sure detects
lung cancer. Majority of lung cancers
are diagnosed or detected when they
are in the late stages meaning they
have spread to nearby organs, lymph
nodes and lungs. Symptoms include
persistent cough, chest pain, difficulty
speaking, pneumonia, bronchitis, and
sputum filled with blood. People who
are at high risk of developing lung
cancer include those who are:
- 60 years of age
or older who currently smoke or have
a past history of smoking
- With chronic obstructive pulmonary
disease (COPD)
- With previous lung tumors
What
are some of the screening techniques
to detect lung cancer early on? Here
is a list of a few:
i) Examination of
molecular markers in sputum
ii) Bronchoscopy (a technique used
to visualize the inside of the airways
and lungs).
iii) Computed tomography (CT) scan
iv) Microscopic analysis of Sputum
cells
Scientists are also
trying to use Chemoprevention agents
including certain Vitamins to try
to stop the development of lung cancer
in patients. A chemoprevention agent
is a substance that can repair genetic
damages before Cancer develops. Examples
of substances that contain Chemoprevention
agents include Retinoids and Selenium.
Chemopreventive agents are not 100%
sure to detect early lung cancer,
not even half the chance. Therefore,
before you consume any minerals or
vitamins containing Chemopreventive
agents, be sure to check with your
medical doctor.
If You Already Have
Lung Cancer
If you already have
lung cancer, it is best advised to
stop smoking immediately. When you
quit smoking, here are the benefits
you achieve over time:
After 20 minutes
- Your blood pressure will drop and
heart rate beats will increase.
After 12 hours -
The amount of Carbon Monoxide in your
blood system drops to normal level.
After 2 weeks -
3 months - Lung function and circulation
of blood from lungs to other organs
of the body improves significantly.
After 1 - 9 Months
- Shortness of breath & coughing
decrease, functions of Cilia (small
hair-like substances that get rid
of Mucus from the lungs) become normal,
your lungs become cleaner, and your
risk of catching infections decreases.
After 1 year - Risk
of Coronary heart diseases drops by
50%
After 5 years -
Risk of Strokes drops to that of a
non-smoker who quit smoking 5-15 years
ago.
After 10 years -
Risk of lung cancer death drops by
50% as well risk of mouth, throat,
esophagus, pancreas or Bladder cancer
also drops.
After 15 years
- Risk of coronary heart diseases
becomes that of a non-smoker.
