When it comes to cold and the flu, Vitamin C or ascorbic acid is hailed as the best remedy and preventive agent. But did you know that this could also help fight against cancer? Vitamin C is a water-soluble vitamin that is not produced by our bodies and needs to be sourced through food. It is needed for the synthesis of collagen, norepinephrine, and carnitine. Collagen is required to develop bones, tendons, ligaments and blood vessels.
Norepinephrine is a neurotransmitter while carnitine is a protein required for transportation of fat to the mitochondria. Vitamin C is also a powerful antioxidant that protects the body against damage caused by free radicals. In addition, it boosts the immune system and increases the body’s ability to fight infections. Ideally, an adult man should have 90mg per day while an adult woman should consume 75mg vitamin C per day.
When it comes to cancer treatment, vitamin C can act as an immune-modulator. It enhances the body’s resistance to pathogens and suppresses production of IL-18. This is a key regulator in melanomas, carcinomas and other kinds of malignant skin tumours. In the case of gastric cancers, the production of IL-18 is boosted by the vascular endothelial growth factor. In the case of breast cancer, IL-18 induces the production of transferrin. Thus, by regulating and reducing the production of IL-18, vitamin C can help reduce the risk of skin cancers, stomach cancers, and breast cancer. Dosage is key to the efficacy of Vitamin C in preventing cancer as an immune modulator.
In its reduced form, vitamin C is known as ascorbate. This has the ability to act as a prooxidant. Ascorbate in high dosages induces apoptosis in some melanomas through mitochondrial dysfunction. Similarly, a low dose of ascorbate induces cell cycle arrest of some types of cancer cells. Thus, by acting as a prooxidant, vitamin C inhibits the growth of cancer cells. This includes growth by inducing endoplasmic reticulum stress, suppressing growth factors and inhibiting angiogenic factor production. It also produces hydrogen peroxide-dependent cytotoxicity in cancerous cells without affecting other healthy cells.
The efficacy of vitamin C in dealing with various types of cancer has been found to be most effective when administered intravenously. In addition, it may also be given orally. Since vitamin C is cytotoxic and does not affect other cells, the side effects of this type of cancer therapy are usually negligible.

Here are screening and treatment of different types of cancers in women
Hello I am Dr. Uma Verma. I am consultant gynecologist in West Delhi, Narayana. Today I will talk about the screening of the cancer in women.
What is screening? Checking your body for cancer before you have symptom increase the chances of detecting certain cancer when they are in most curable stage. First I will talk about cervical cancer. Cervix is the lowermost part of the womb. This is the only cancer which is preventable and it has a very long indolent part present as a precancer region. Nowadays vaccine is also available to prevent this cancer. Pap smear is the ultimate screening of chest to prevent the cervical cancer. Once we start screening Pap smear 3 year after the first intimate relation from 21 to 29 years of age yearly and after 29 it should be done with the HPV virus detection. It can be done till 65 years of age and later also if anything abnormal with the Pap smear, patient can go further for the rompers copy also.
Second cancer we are going to discuss is about the breast cancer. We have the Mammogram Manual examination of the breast and MRI. Self examination of the breast is controversial issue, It should be done or not. Some authorities say to be done, some say it is of no use. If at all it should be done it should be started at age of 29 till 40. It should be done with three early and after 40 year it should be done annually. Candidate for the genetic testing, Personal history of CA breast should undergo genetic testing for the breast cancer. Close relative having history of breast, prostate or unaware cancer. Breast cancer developing before the age of 50 having both the breast in ovarian cancer, near relative having the breast cancer, Easter European, Jewish ancestors, anybody who is having ovarian cancer, these are all above the position should be genetically investigated for the screening of the breast cancer.
Now we come to ovarian cancer. This is the ninth most common female cancer. The test used for the click screening is CA 125 and trans vaginal sonography. There is no reliable way to screen for the ovarian cancer in women who do not have any sign. Screening should start at 30 to 35 years that is 5 to 10 year areas when the cancer detected in youngest member of the family. Screening does not reduce death from the cancer in general population. 20 to 25% of the women diagnosed with ovarian cancer have the heriditary tendency. Now come to the uterine cancer screening.
For the uterine cancer there is no screening way. We only have Diagnostic test that Diagnostics test are Endrometrial sampling, DLC, hysteroscopy and also we have the ultrasound to see the endrometrial sickness. Now come to the Colorectal cancer. Colorectal cancer screening is to begin at the age of 50. In this we do high sensitivity fecal occult blood testing, colonoscopy and sigmatoscopy. It should continue annually till the age of 70. That is all.
In summary I want to tell the cancer screening is important so that we can treat the disease at earliest possible. And when the disease is detected earlier the chances vof cure is high. Once the patient develop the disease then nobody knows what is going to happen. Two cancer in the females are the cervical and breast which needs definite screening for the general population as well as for the high risk population. Breast cancer the screening is not of much use.
That is all. Thank you

The prostate gland in males surrounds the urethra, through which urine and sperm are passed out of the body. Its function is to secrete a fluid, which provides nourishment to the sperm. It is about the shape of a walnut and is present between the pubic bone and the rectum.
As a man crosses 40, the prostate gland begins to increase in size due to an increase in the number of cells. This is known as hyperplasia. The condition is usually benign and therefore the name benign prostate hyperplasia (BPH). As it continues to grow, there is an increased pressure on the urethra. Therefore, there can be problems with urination. The bladder, being a muscular organ, compensates to some extent and so the problems with urination are mostly managed. If left untreated, this can continue to be a major problem and the bladder may not be able to compensate. In men who are 60-plus, BPH is very common.
Signs and symptoms
- One of the initial symptoms of BPH is when the urine stream begins to grow weak.
- There could also be a reduced speed of passing urine.
- Men with BPH never have a feeling of complete emptying of the bladder.
- On the other hand, there is also a constant difficulty in initiating a urine stream. There could be intermittent breaks in the urine stream.
- The person may feel the need to strain to initiate the stream and to ensure complete emptying.
- There could be dribbling of urine after passing urine.
- The duration between two bathroom visits can constantly reduce, with the constant urge to urinate.
- There is a constant urge to visit the bathroom, which is more common in the night. One of the most annoying features of BPH is the walking up at night to urinate, but with an inability to initiate a stream and an inability to completely empty the bladder, it leaves the person very irritated and frustrated.
- There could be blood in the urine. In fact, blood in the urine accompanied by fever, chills, nausea and vomiting are indications of an emergency.
- There could be blockage of urine completely, if the enlargement is quite severe.
If you are having any of these symptoms, then the doctor will first test for an enlarged prostate through a digital rectal exam. Then a test is done to check a chemical called prostate specific antigen. Increased levels of this chemical is almost always indicative of BPH. In addition, X-rays and scanning may be used to confirm diagnosis.
Though medications are available, confirmatory treatment is through surgical removal. The procedure needs a inimum of 2 to 3 days. In case you have a concern or query you can always consult an expert & get answers to your questions!
