Brain cancer is a disease of the brain in which cancer cells (malignant cells) arise in the brain tissue. Cancer cells grow to form a mass of cancer tissue (tumor) that interferes with brain functions such as muscle control, sensation, memory, and other normal body functions. Tumors composed of cancer cells are called malignant tumors, and those composed of mainly non-cancerous cells are called benign tumors. Cancer cells that develop from brain tissue are called primary brain tumors while tumors that spread from other body sites to the brain are termed metastatic or secondary brain tumors.
Brain cancer is actually the abnormal growth and uncontrolled growth of the cancer cells in the brain that forms a tumor in the brain.Tumours can be either benign or malignant.
Benign brain tumours are abnormal collections of cells that reproduce slowly and usually remain separate from the surrounding normal brain.
Malignant tumours reproduce and grow quickly. Their borders are hard to distinguish from the normal brain around them.
There are few early symptoms of brain cancer, but as the tumour grows within the confines of the skull, it causes increased intracranial pressure and exerts pressure on the brain, causing signs to develop.
Brain cancer symptoms and signs are varied and depend on the area of the brain involved, but can include:
Nausea and vomiting, which, CANSA reports, may be worse in the morning or after a sudden position change.
Difficulty walking or clumsiness.
Changes in alertness.
Brain cancer occurs when there is an uncontrolled growth of cancer cells in the brain that form a malignant brain tumor. The underlying cause of primary brain cancer, cancer that begins in the brain, is not known. Secondary brain cancer is caused by a cancer of another organ in the body, such as the breast, prostate, kidney, skin, or bone, that has spread to the brain.
What are the risk factors for brain cancer?
Certain inherited conditions, including neurofibromatosis, Von Hippel-Lindau syndrome, Li-Fraumeni syndrome, and Turcot syndrome
Personal history of cancer or family history of brain cancer
Impaired immune system
Radiation therapy of the head
Surgery is the main form of treatment for brain tumors that lie within the membranes covering the brain or in parts of the brain that can be removed without damaging critical neurological functions. The goal is to remove the entire tumor, whenever possible, as a tumor may recur if any tumor cells are left behind. Radiation therapy and chemotherapy are generally used as secondary treatment for tumors that cannot be cured through surgery alone.
Stereotactic radiosurgery is a treatment option that delivers a high concentration of radiation directly to the tumor in order to stop its growth, while delivering only a minimal dose of radiation to the surrounding tissue. Unlike conventional surgery, stereotactic radiosurgery does not require making an incision to remove the tumor. It can be especially effective in patients with many small metastatic brain tumors. If you wish to discuss about any specific problem, you can consult a doctor and ask a free question.
Medical science constantly challenges the boundaries by finding not only the cures to the most dangerous diseases, but finds a way to prevent them even before they occur. With years of research, practice and data available for analysis, scientists are using advanced technology in combination with years of research to create a predicting mechanism for often fatal diseases like cancer.
Breast cancer screening has always been done with mammography. The fact is that this method is only 75% accurate, laden with false positives and misses a whole set of women totally- and that too when cancer has already developed. Part of the problem comes from the dense breast tissue which one in three women have. This tissue masks the lumps, which makes it difficult for mammograms to accurately screen cancer.
Some breakthrough scientific methods are changing this by drawing on years of research to predict this deadly disease, years before it can manifest itself.
A genetic test to predict cancer 10-11 years ahead of time
This test was performed to see how environmental factors could influence cancer, along with habits like smoking, abusing alcohol or hormones, genetic changes that occur and are put a large percentage of the women at a high risk of developing this disease.
A simple blood test is used for the genetic analysis of hereditary cancer. Researchers found a biological marker, methylation of the ATM gene, which has a very high ability to predict the risk of developing cancer, several years before diagnosis. 'Methylation' concluded that when one biological indicator is exposed to carcinogenic substances, or other abusive substances like tobacco and alcohol, it may trigger the development of cancer. On the flip side, this test will take time to reach the commercial market and even then cannot give an exact timeline as to when someone may develop the disease.
A simple blood test to predict breast cancer 5 years before it develops
This is the kind of medical miracle the world is looking for. Last year in April, researches in Denmark identified a simple blood test that can predict breast cancer five years before it actually develops with an accuracy of a whopping 80%.
It works by "measuring all of the compounds in the blood to build a 'metabolic profile' of an individual, in order to detect changes in the way chemicals are processed, during a pre-cancerous stage," says Laura Donnelly, health editor at The Telegraph, which covered this development. Danish researchers observed 57,000 participants over 20 years, gathering blood samples along the way, specifically comparing a set of 800 women who remained healthy or developed breast cancer within 7 years of their first blood sample. The researchers found they were able to predict, with 80 percent accuracy, which patients would be affected by the disease, just by looking at the metabolic profiles they built from the participants' blood samples. The results have been published in Metabolomics.

Cancer is an uncontrolled proliferation of transformed cells in any part of the body. Neoplasm or tumor are used variably to describe any swelling or new growth. Benign growths don't have the potential to spread to other organs or parts of the body while malignancy or malignant growths have uncontrolled proliferation and metastatic potential. Transformation is a multistep process with genetic alterations by which normal cells acquire malignant potential, uncontrolled proliferation capacity and capacity to spread to other parts of the body (metastasis) worldwide cancer is responsible for 1 in 8 deaths. Most common cancers are:
Men: oral cancer (in India), prostate, lung
Women: breast, cervix and endometrium, colorectal, lung
What causes cancer? cancer is usually multifactorial
1. Age- more in age group greater than 60 yrs compared to younger age group
2. Obesity- body mass index greater than 30
3. Tobacco - cigarette, cigar, bidi, hookah, smokeless tobacco like gutka, zarda etc. There is no safe form of tobacco.
4. Pan masala and supari
6. Ultraviolet rays exposure
7. Radiation exposure
8. Genetic factors
9. Others- pollution, certain chemicals, infections
Prevention of cancer:
1. Stay away from tobacco products
2. Eat healthy and daily physical activity- fresh fruits and vegetable are good, maintain optimal body weight
3. Be safe in sun
4. Cancer awareness and early detection: alarming signs are (caution)-
- Change in bowel or bladder habits
- A sore that will not heal
- Unusual discharge or bleeding
- Thickening or lump in the breast, testicles or elsewhere
- Indigestion or difficulty swallowing
- Obvious change in a wart or mole
- A nagging cough or hoarseness
5. Cancer screening: screening is for healthy individuals with education. Rather than going for unnecessary blind tests, a programme for screening should be planned in consultation with your oncologist as requirements are different for different cancers and differ as per age groups and gender. Also, screening is not effective in all cancers. Cancer education and awareness have due importance. Some cancers in which screening has been shown to be effective includes breast, colon, rectum, cervix, prostate, lung in high-risk groups but as mentioned earlier it is planned with participation of both individual and oncologist.
Types of cancer treatment:
Cancer treatment is now a multidisciplinary management in which different surgical, medical and radiation oncologist plan treatment protocol for best possible chances of cure. Advancement in all these fields and their contribution in comprehensive management results in 25-30% improvement in cure rate over previous decades.
- Surgery: involves surgical principles to remove the tumor with adequate margins and possible draining lymph nodes regions. Improvements and understanding of surgical principles even make resection of distant disease or cure of stage iv disease in some selected cases.
- Chemotherapy: cytotoxic drugs are given either in injectable or oral forms which acts on uncontrolled cancer cells. Advances in this fields result in drugs with better efficacy and less side effect profile and at the same time resulting in better cancer control. Targetted therapy acts on specific pathways of cancer growth. Hormone therapy targets specific hormone receptors for controlling cancer.
- Radiation therapy: is the delivery of radiation generated by radioactive source over the region of cancer. More and more advances in radiation technologists are emerging like imrt, sbrt to focus radiation over the specific location so as to avoid toxic effect over surrounding area.

Being diagnosed with cancer is something no one looks forward to and Gynaecological Cancer is every woman’s worst nightmare. However, if diagnosed in time, it can be treated. Cancer in any part of a woman’s reproductive system is termed as gynecological cancer. It is of five types:
Paying attention to your body and understanding its natural rhythm can help you recognize signs of gynecological cancer. This is because signs of gynecological cancer can be difficult to identify unless you know your body. Here are a five signs to watch out for-
Abnormal Vaginal Bleeding: Bleeding in between periods is okay once in a while but if it happens continuously over a period of 2 to 3 months, do not ignore it. Vaginal bleeding after menopause should also never be ignored. Abnormal bleeding could be triggered by a number of conditions including cancer of the lining of the uterus. Sudden changes in your menstrual blood that persist for over 2 cycles such as heavy bleeding can also be a symptom of uterine cancer. Heavy bleeding can be defined as a period that lasts for over 7 days.
Changes in the Vulva: Any change in colour of development of bumps, sores of thickened skin should be immediately shown to a gynecologist. Any form of vulvar itching or burning should also not be ignored. These conditions could be symptoms of vulvar cancer. Hence, it is important to know what your vulva looks like normally.
Bloating: Persistent bloating that lasts for over a fortnight can be a sign of ovarian cancer. This is especially true in cases of bloating accompanied by sudden weight loss or between-period bleeding.
Change in Bathroom Habits: Due to the proximity of the bladder to the reproductive organs, a tumour or swelling in the reproductive organs can trigger symptoms similar to those of a urinary tract infection. This includes pain while urinating, difficulty passing urine, diarrhea or constipation. Urinary incontinence could also a sign of gynecological cancer.
Abdominal or Back Pain: In rare cases, lower back pain could be a sign of ovarian cancer or uterine cancer. Pain in the lower abdomen or pelvic area can also be a sign of ovarian cancer.
The above could also be signs of other health disorders. The only way of knowing for sure is by consulting a doctor. Hence, understand your body and if you notice any of these symptoms consult your gynecologist at the earliest.
