Colorectal Cancer Prevention

Colorectal Cancer Prevention

Colorectal cancer patients  seem be getting younger and younger. Patients between the age of 40 to 50 has tripled in the past 20 years.  60% of colorectal cancer occurred in the last two feet of the large intestine - the sigmoid colon to the rectum.  In fact, colorectal cancer is usually caused by intestinal polyps. The key to prevention is early detection and removal of intestinal polyps, so to prevent it from developing into malignant colorectal polyps.

Both men and women should have regular check-ups once reached the age of 50.  Here are some options:

Option 1- Fecal Occult Blood Test

The most basic method  is to receive annual FOBT (Fecal occult blood test), which is a test to see if stool contains  invisible blood.  If the test is positive, further procedure, such as colonoscapy, needs to be done.

Option 2- Sigmoidoscopy

Conduct sigmoidoscopy once every five years.  Endoscopic length is short, only up to the sigmoid colon.

Option 3- Fecal Occult Blood Test + Sigmoidoscopy

FOBT annually AND sigmoidoscopy once every five years.

Option 4- Colonoscopy

Colonoscopy once every five years, which can reach the entire colon.

Generally speaking, people with family history of colorectal cancer or intestinal polyps previously found are at high risk group.  This group should begin regular check-ups at a younger age, and procedures should be done more frequently. If polyps are found during the colonoscopy procedure, doctors can remove them immediately.

What is Benign prostatic hyperplasia?

What is Benign prostatic hyperplasia or Prostate Enlargement?

One in every two men over the age of 50 may suffer from "Benign prostatic hyperplasia". Although there is no way to prevent it, but surgery may prevent bladder dysfunction and kidney failure, as well as other serious complications in the future.

Why can't benign prostatic hyperplasia be prevented? Urology specialist explained that the prostate growth is stimulated by male hormones; as long as hormones continue to release, prostate will continue to grow, it will not stop.

1. Obstructive symptoms

  • pause before urinating
  • prolonged urination; most people only need a minute and a half, but the patients of benign prostatic hyperalasia  may take up to  three minutes
  • "stop and go" during urination
  • drops of urine after urinating

2. Irritant symptoms

  • frequent urination: most people urinate four to six times a day (depending on the amount of water consumed), but patients of benign prostatic hyperalasia may need to use the restroom every hour
  • nocturia; at least 2-3 times per night
  • cannot control urination, which may lead to incontinence

Aspirin can prevent Cancer?

Aspirin can prevent Cancer?

New research has shown that aspirin has the ability to prevent cancer, especially Colorectal Cancer and Stomach Cancer.

Here is a list of cancers that aspirin may prevent:

  • Colorectal Cancer
  • Stomach Cancer
  • Prostate Cancer
  • Lung Cancer
  • Brain Cancer
  • Throat Cancer
  • Breast Cancer

The study shows a small amount of aspirin taken daily may significantly reduce the risk of death caused by a variety of cancer.

Dr. Peter Rothwell of John Radcliffe Hospital of Oxford University and his colleagues reviewed eight clinical trials in the United Kingdom; over twenty-five thousand five hundred people participated in the trial. Testing times ranged from 4 to 8 years. It was found that subjects taking as much as 75 mg of aspirin daily for over 20 years, cancer mortality rate can be reduced by 20%, of which colorectal cancer mortality rate can be reduced to 40%, lung cancer to 30%, esophageal cancer significantly reduced to 60%.  Other causes of mortality had also decreased by 10%, the effects of cancer prevention can last up to 20 years.

It is most effective when taking aspirin for 5 year. Mortality rate can be reduced  to 30-40%, depending on the type of cancer.

However, Lesley Walker,  member of the British Association for Cancer Research (Cancer research UK) has warned that the study is still not mature; taking aspirin to prevent cancer should not yet be recommended at this point.

Side effects and precautions of Aspirin:

Gastrointestinal effects: abdominal discomfort and nausea, and stomach bleeding. Therefore, aspirin should be taking with food and antacids (when needed) to reduce irritation. Patients with stomach ulcers should take aspirin with extra caution. Alcohol should be avoided when taking aspirin.

Acid reaction: nausea, vomiting, tinnitus, headache, dizziness when overdose.  Ggastric lavage, catharsis, or oral sodium bicarbonate may be needed.

Allergic reactions: Angioneurotic edema, asthma or anaphylactic shock may occur. Therefore,  patients with asthma should not take aspirin.

Radiation found in California Milk

Radiation found in California Milk
On March 31, 2011, U.S. Environmental Protection Agency & FDA has detected small amount of radioactive iodine-131 in California milk sample.  The iodine-131 found is 5000 times lower than the FDA limit, so drinking these low radiation milk should not increase cancer risk.

The good news is the half life of iodine-131 is eight days which means the level of radiation will drop by half in eight days.  As long as the situation of Japan's Fukushima Daiichi nuclear plant under control, there should be not health risk on consuming California milk.

The most toxic element Plutonium found in Japan soil

The most toxic element Plutonium found in Japan soil

What does it mean to you when Plutonium, the most toxic element, was found in Japan soil? We have heard iodine I-131, I-133 and Uranium-238 found in air, seawater, and soil in the last few days. However, more radioactive elements has been found by the Japanese Government,  including the deadly Plutonium 239. What does it means to us?

Plutonium is raw materials used to make nuclear weapon. It accumulates in bone marrow and causes leukemia and bone cancer. It has a  half-life of up to 24,000 years, which requires a very long time to be decomposed in the environment. Plutonium is worse than iodine, cesium and other radioactive materials; its has long term effects on generations to come.  If plutonium contamination spreads to underground water, the situation is even worse.  The Japanese Authority may have to shut down nuclear power plant and  spend decades on  cleaning up the nuclear contamination.

Some scientists have stated that five grams of Plutonium 239, which is approximately the size of one cube of sugar,  can kill all humans and living creatures in the world!! However, this highly radioactive Plutonium particles cannot travel in long distances. It does harm to you when you inhale them; it does not penetrate through human skin. Also, their deadly radiation nature increase the risk of bone cancer, liver cancer, and leukemia.

Radiation and Pregnancy

Radiation and Pregnancy

People panic about radiation. Physician stated that organs begin to form in fetus between 2 to 7 weeks of pregnancy; 8 to 15 weeks of pregnancy is the early formation of the fetus. These stages are most vulnerable to effects of radiation. However,  radiation must reach 100 to 200 millisieverts  (mSv) to cause fetal malformations.

If a pregnant women is affected by 50 to 500 millisieverts (mSv) of radiation during these two stages,  central nervous system will be affected and the main organs of the fetus will be developed abnormally. Growth may slow down and lead to severe mental retardation. If affected by over 500 millisieverts (mSv), it will increase the chances of miscarriage. If the fetus has reached 26 to 38 weeks, the rate of stillbirth or dead of premature newborn may increase significantly.

The child may have cancer when grown up regardless of the degree of radiation exposure; especially leukemia, the risk of the child having leukemia increase by 12% for every 1,000 mSv of radiation. The average IQ will also drop from 25 to 31 points; the child may be 3 to 4% shorter than the average height by the age of 18.

However, 1,000 mSv of radiation would mean going though X-ray procedures continuously for a couple of hundred times, therefore, when living in a  environment with an acceptable level of radiation, pregnant women do not need to be overly worried.

Know more about Acute Radiation Damage

Acute radiation damage

Ionizing radiation will destroy the chemical balance of tissues, the role of intracellular molecules and free radical formation, which causes a specific biophysical (biophysical) change in the body. This article will provide you with information on early signs and damage and emergency care of ionizing radiation.

Acute Radiation Symptoms  (ARS)

Exposure to hundreds or thousands of RADs (Roentgen Absorbed Dose) of the radiation field for a few minutes will lead to acute radiation symptoms (acute radiation syndrome). Because cell's  sensitivity to radiation varies, it takes time for different damage symptoms to appear after acute, over exposure.

1. The first/ immediate (prodromal) phase

Prodromal means leading, it also represents the start of the disease (initial stage). As low as 50 RADs can cause prodromal symptoms, prodrome will occur within a few minutes of exposure to more than 1,000 RADs of radiation.  Symptoms include nausea , vomiting, and diarrhea, it is also known NVD symptoms.

2. Latent period

After the prodromal symptoms, latency (latent period) may follow. There are no signs of physical injuries. In fact, lethal effects or recovery process has just begun.The second phase, latent period, may last from a few hours to a few weeks, depending on the amount of radiation absorbed.

What is Radiation Contamination?

What is Radiation Contamination or Radiation Infection?

After the explosion of nuclear power plant in Fukushima Prefecture, Japan,  a local television station immediately alert nearby residents to stay indoor and hedging, turn off, and stop drinking tap water. Those who are in outdoor should avoid exposing their skin and cover faces with wet towels and face masks.  International Atomic Energy Agency said that Japanese authorities are prepared, ready to distributed iodine to residents for to treat radiation affection.

Radiation power is strong. In the event of nuclear explosions, radioactive material will leak out as smoke and wind diffusion. People that are  affected by radiation may suffer from damage in hematopoietic and gastrointestinal functions, and central nervous system.  While long term effects may include development of cataract, cancer, and birth defects.

Early radiation effects on human beings when  iodine I-131 and I-133 are gathered in our body; it will be gathered in the thyroid and cause cancer, treatment is to take iodine tablets.  With no occupation of radioactive iodine in the thyroid, radioactive iodine will not be gathered in the body .

Onions and Allicin

Onions and Allicin

Doesn't matter how strong you are, you must have cried when you cut onions. Registered dietitian said onion, green onions and garlic contain allicin, an antioxidant that helps reduce free radical damages to cells; it prevents vascular aging and cancer. According to the World Cancer Research Fund's expert report, consumption of vegetables with allicin  (including onion) will help prevent stomach cancer. In addition, onions are rich in natural sugar, vitamin C and potassium; a medium-sized onion contains about forty-four calories. Onion has a very unique taste, which is suitable for use as seasoning or garnish.
