How does Vitamin C Kill Cancer Cells?

Vitamin C‘Vitamin C can kill cancer cells’ has been always believed to be a myth until University of Iowa’s redox biology expert Garry Buettnerhas and his team has proven that high dose vitamin C given intravenously can kill cancer cells.

Usually vitamin C therapy involves taking vitamin C supplements orally, but professor Garry Buettner and his team has found that when vitamin C supplements are taken orally, natural metabolic mechanism limits its absorption to (systemic circulation) blood stream and subsequently it has less effectiveness in terms of killing cancer cells.

However, Professor Garry Buettner and his team has found that when vitamin C is given via intra venous ( through vein ) thus bypassing normal gastrointestinal metabolism and excretion pathways—creates blood levels that are 100 to 500 times higher than levels seen with oral ingestion. This high level of Vitamin C in the blood directly attacks cancer cells.

Earlier work by Professor Garry Buettner found that these extremely high level of vitamin C kills cancer cells and don’t harm normal cells in test tube and in mice. Doctors at university of Iowa are now testing the approach in clinical trials for pancreatic cancer and lung cancer that combine high-dose, intravenous vitamin C with standard chemotherapy or radiation. Earlier phase 1 trials indicated this treatment is safe and well-tolerated and indicated that the therapy improves patient outcomes. 

The Role of Vitamin C killing Cancer Cells
In a new study published in December issue of the Journal of Redox Biology, Buettner and his colleagues have explained the mechanism how high dose of vitamin C kills cancer cells. The study reveals that vitamin C break down easily, forming hydrogen peroxide ( a free radical), which can damage human tissue and DNA, but the researchers further found that the healthy cells seemed to have self-defensive mechanism that easily allowed them to resist the oxidizing effects of hydrogen peroxide. However, tumor cells are more prone to get damaged and destroyed by the chemical.

“In this paper we demonstrate that cancer cells are much less efficient in removing hydrogen peroxide than normal cells. Thus, cancer cells are much more prone to damage and death from a high amount of hydrogen peroxide,” says Buettner, a professor of radiation oncology and a member of Holden Comprehensive Cancer Center at the University of Iowa. “This explains how the very, very high levels of vitamin C used in our clinical trials do not affect normal tissue, but can be damaging to tumor tissue.”

Do not attempt to use this treatment by yourself. This treatment must be used under the direction of cancer experts who are based at a clinic.

7 Prostate cancer warning signs that you shouldn’t ignore

Prostate cancer warning signsIn this article I’m going to focus on 7 prostate cancer warning signs that you shouldn't ignore. According to the American Cancer Society, Prostate cancer is the most common cancer among men in the US and fourth most cancer overall. The incident of prostate cancer rises with increasing age.  The exact causes of the prostate cancer is unknown and it’s noticeably very rare among young men. All the signs and symptoms are related to the size and growth of prostate tumor.

5 Colon cancer warning signs that you should not ignore 

1. Hesitancy

You may feel your bladder is full and may want to pass urine, but then you have to wait for a long time before the urine stream starts. The main reason for hesitancy is due to the enlargement of the prostate gland, usually it is because of benign prostatic hyperplasia (BPH). And also due to the pressing of urethra by the prostate tumor.  If you are having hesitancy of urination, this may be a prostate cancer sign and it’s advisable to see a doctor as soon as possible.

2. Frequency

You may experience increased urination than usual. Especially during night time you may wake up due to the feeling of bladder fullness. Medically it is defined as nocturia. Normally, you should be able to sleep six to eight hours without having to wake up to go to washroom. Usually, people who are having nocturia wake up more than once. Frequency of urination can be assumed as a prostate cancer warning sign. But frequency of urination is also a sign of urinary tract infection.

3.Poor Stream

Poor urine stream is another prostate cancer warning sign that you should not ignore. Poor urine stream means, urine comes out more slowly and with a less force than usual. Poor stream may be due to the pressing of urethra by the enlarged prostate.

4. Urgency

The desire to pass urine is regularly more than it used to be. This is due to sudden involuntary contraction of the muscular wall of the bladder. Urgency to pass urine can be considered as prostate cancer warning sign. However, the urgency may also be due to some other urological problem. It is always advisable to see a doctor to rule out the exact cause of urgency.

5. Dribbling

When you have finished passing urine, the urine continues to dribble out or drip out. Some people call it as male version of urinary incontinence. Usually, men refuse to talk about that, but it can be a prostate cancer waning sign or either urological urgency. You need to see the doctor as soon as possible.

6. Blood in the Urine


Urine may contain red blood or may be smoked color. The tumor in the prostate bleeds and the blood is found in urine. This sign is usually seen in the late stage of cancer but urine in the blood can be identified by doing a simple laboratory test. Medically it is called hematuria. Hematuria is also usually related with many other urological conditions. If you can observe smoked, cloudy urine or pinkish colour in the urine, you should see the doctor to rule out whether it is prostate cancer warning sign or other urological abnormal conditions like UTIs.

7. Pain in the lower abdomen or Pelvic region

Unexplained pain or tenderness in the lower abdomen or pelvic region without any particular reason is also a prostate cancer warning sign that you should pay attention and see the doctor. The pain may be due to the extension or spread of tumor to the lower back, hip and pelvis.

These signs and symptoms can be seen at late stage of prostate cancer. Since it has no symptoms at all in the early stage, it is difficult to diagnose.
