Cancer- General Information: Don't Fear, Be Aware

Cancer

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

5. Alcohol

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.

What is the main cause of cancer or tumor? Do we really know the causative agent for cancer?

MBBS
General Physician, Faridabad
Genetic changes that cause cancer can be inherited from our parents. They can also arise during a person’s lifetime as a result of errors that occur as cells divide or because of damage to DNA caused by certain environmental exposures. Cancer-causing environmental exposures include substances, such as the chemicals in tobacco smoke, and radiation, such as ultraviolet rays from the sun.

What are the causes of cancer and what are its symptoms and and what are its effect on humans?

DNB, MBBS
Oncologist, Faridabad
Dear sir, cancer is caused by some abnormal signal which usually control the growth of the cells. They are triggered by some carcinogens like tobacco, pollution, pesticides, industrial affluent, radiation exposure etc. They usually present as lump, mostly painless, unexplained weight loss, fever, anaemia, fatigue, non healing ulcer, difficulty in swallowing, altered bowel habits, bleeding etc. When there is uncontrolled growth of cells they start exausting body resources causing weakness, fatigue and organ failure and then start moving to other organs and effect their function aswell.

Top 4 Symptoms Of Liver Cancer

Top 4 Symptoms Of Liver Cancer

If you are concerned about liver cancer, you should know that most people do not experience signs and symptoms of the cancer in the early stages. Liver cancer is a form of cancer which occurs in the cells of the liver. There are various types of cancer which can develop in the liver. Hepatocellular carcinoma (HCC) is the most common liver cancer which begins in the hepatocyte, which is the main liver cell.

Symptoms-

Usually there are no specific primary stage symptoms of liver cancer. Some symptoms which may develop include the following:

  1. Unusual weight loss is observed

  2. Loss of appetite and developing food aversion

  3. Pain in the upper abdomen

  4. Nausea followed by vomiting

  5. General weakness with intense fatigue

  6. Swelling in the abdomen

  7. The skin may become yellow

  8. White and chalky stools are likely

Causes-

In most cases, the causes of liver cancer cannot be clearly determined. In some cases, the cause is known, such as chronic infection with the hepatitis virus, which may lead to liver cancer. Liver cancer occurs when the liver cells undergo changes or mutations in their DNA structure. DNA mutations lead to changes in instructions of chemical processes taking place in the body. The cells may grow out of control and develop into a cancerous tumour.

Risk Factors-

There are several factors which enhance the risk of liver cancer. They are as follows:

  1. Chronic infection with hepatitis B or hepatitis C increases the risk of liver cancer.

  2. A progressive and irreversible condition known as cirrhosis leads to scar tissue formation in the liver, increasing the risk of liver cancer.

  3. Certain inherited liver diseases such as Wilson’s disease and hemochromatosis also increase the chances of liver cancer.

  4. People with diabetes are also at a greater risk of having liver cancer.

  5. Non-alcoholic fatty liver disease (NAFLD), which is the accumulation of fat in the liver, also increases the chances of getting this condition.

  6. Excessive alcohol consumption is another factor which causes irreversible damage to the liver and the chances of getting liver cancer get boosted.

  7. Exposure to aflatoxins, which are poisons produced by molds growing on poorly stored crops, make you more likely to get liver cancer.

Several tests and procedures are carried out for the diagnosis of liver cancer. These include blood tests for diagnosing liver function problems, and imaging tests such as ultrasound, CT scan and MRI scan.

What are the symptoms of mouth cancer what types of precautions and medicine should be taken?

MS ( General Surgery)
Oncologist, Mandsaur
Oral cancer symptoms Some of the most common oral cancer symptoms and signs include: •Persistent mouth sore: A sore in the mouth that does not heal is the most common symptom of oral cancer •Pain: Persistent mouth pain is another common oral cancer sign •A lump or thickening in the cheek •A white or red patch on the gums, tongue, tonsil, or lining of the mouth •A sore throat or feeling that something is caught in the throat that does not go away •Difficulty swallowing or chewing •Difficulty moving the jaw or tongue •Numbness of the tongue or elsewhere in the mouth •Jaw swelling that makes dentures hurt or fit poorly •Loosening of the teeth •Pain in the teeth or jaw ••Voice changes •A lump in the neck •Weight loss •Persistent bad breath If any of these oral cancer symptoms or signs are present for days or weeks, your doctor may recommend tests to check for oral cancer. As with any cancer, having your cancer diagnosed as soon as possible will help ensure that any treatment is as effective as possible. Screening for oral cancer Although routine screening for oral cancer is not typically recommended, several tests can be done if any of the symptoms of this disease are present and do not go away. Oral cancer risk factors GENERAL •Gender: Oral cancer and oropharyngeal cancer are twice as common in men as in women. This difference may be related to the use of alcohol and tobacco, a major oral cancer risk factor that is seen more commonly in men than women. According to the American Cancer Society, the gender difference is decreasing among oral cancer patients as more women are using tobacco and drinking. •Age: The average age at diagnosis for oral cancer is 62, and two-thirds of individuals with this disease are over age 55. •Ultraviolet light: Cancers of the lip are more common among people who work outdoors or others with prolonged exposure to sunlight. Poor nutrition: Studies have found a link between diets low in fruits and vegetables and an increased oropharynx and oral cancer risk. GENETICS •Genetic syndromes: Some inherited genetic mutations, which cause different syndromes in the body, carry a high risk of oral and oropharyngeal cancer. These include: •Fanconi anemia: This blood condition is caused by inherited abnormalities in several genes. Problems can begin at an early age and often lead to leukemia or aplastic anemia. The risk of oral cancer among people with Fanconi anemia is up to 500 times higher than among the general population. •Dyskeratosis congenita: This genetically linked syndrome can also cause aplastic anemia, and carries a very high risk of mouth and throat cancer occurring at an early age. LIFESTYLE •Tobacco use: About 80% of people with oral cavity and oropharyngeal cancers use tobacco in the form of cigarettes, chewing tobacco or snuff. The risk of developing oral cancer depends on the duration and frequency of tobacco use. Smoking can lead to cancer in the mouth or throat, and oral tobacco products are associated with cancer in the cheeks, gums, and inner surface of the lips. •Alcohol: About 70% of people diagnosed with oral cancer are heavy drinkers. This risk is higher for people who use both alcohol and tobacco. For people who smoke and drink heavily, the risk of oral cancer may be as high as 100% more than the risk for people who do not smoke or drink. •Betel quid: Many people in Southeast Asia, South Asia, and others parts of the world chew betel quid, a leaf from the betel plant wrapped around areca nut and lime. Chewing gutka, a combination of betel quid and tobacco, is also common. Both of these substances are associated with an increased oral cancer risks. OTHER CONDITIONS •Human papillomavirus (HPV) infection: Human papilloma viruses, or HPV, include about 100 similar viruses. Many HPVs cause warts, but some are involved in cancer. Most noteworthy, HPV is tied to the development of cervical cancer. HPV is also a risk factor for oral and oropharyngeal cancers. About 25 percent of patients with these cancers are infected with the same HPVs as are seen in with cervical cancer. In particular, there is a strong link between HPV-16 and oropharyngeal cancer. HPV appears to be a more serious risk factor for oropharyngeal cancer than for oral cavity cancers. People with oral cancers linked to HPV tend to not be smokers or drinkers, and usually have a good prognosis. Typically, HPV infections in the mouth and throat do not produce any symptoms, and only a small percentage of these infections develop into cancer. Read about the recent increase in HPV-related cancers. •Immune system suppression: Taking drugs that suppress the immune system, such as those used to prevent rejection of a transplant organ or to treat certain immune diseases, may increase the risk of oral cancer. •Lichen planus: People with a severe case of this illness, which usually causes an itchy rash but sometimes appears as white lines or spots in the mouth and throat, may have a higher risk of oral cancer. Lichen planus usually affects middle-aged people. •Graft-versus-host disease (GVHD): This condition can occur after a stem-cell transplant, in which bone marrow is replaced following cancer occurrence or treatment. The new stem cells may have an immune response against the patient’s own cells, and tissues in the body may be destroyed as a result. GVHD increases the likelihood of oral cancer, which can develop as soon as 2 years later. UNPROVEN RISK FACTORS In recent years, concern has been raised about some products heightening the risk of oral cancer. These concerns are controversial and have not yet been proven in scientific studies. The products some believe to increase cancer risk factors include: Mouthwash: Some studies have shown a link between mouthwash that is high in alcohol content and the risk of oral and oropharyngeal cancer. However, other research has raised doubts about this concern. The frequent use of mouthwash by people who smoke and drink—two confirmed risk factors for oral cancer—makes it difficult to establish a clear link between mouthwash and oral cancer. •Irritation from dentures: Poorly fitting dentures that cause long-term irritation of the mouth lining have also been a point of concern regarding oral cancer risk. This link has not been confirmed in several studies. However, loose dentures may trap substances that are known to cause oral cancer, such as alcohol and tobacco. Individuals who wear dentures should be sure to have their fit checked by a dentist regularly, remove them at night, and clean and rinse them thoroughly each day.
