Cancer and Biopsy

Cancer and Biopsy

Cancer is a deadly disease in which cells of any body part begin to grow abnormally, harmfully and randomly, until these extra cells take the form of acne, or tumors. The main cause of cancer is the DNA in the cells, which naturally changes and divides the cells in a continuous and abnormal way. This change is called mutation in medical terms. That is, one to two, two to four, four to eight. And in the same order, the growth of unnecessary cells continues. There could be several reasons for this change in DNA.

For example, smoking, alcohol, blisters, gutka use, exposure to too much sun, drinking hot tea or coffee, canned foods or frozen foods, and the use of chemical preservatives. In general, the immune system eliminates invading germs. But cancer cells combine with the body's own cells. Therefore, the immune system does not recognize these cells and thus they begin to grow in the body. Cancer can affect people of any age.

Symptoms of Cancer

Common symptoms include tumors, pain, and weight loss, as well as symptoms related to the part of the body where it appears. For example, if you have esophageal cancer, you may find it difficult to eat or drink anything. Similarly, lung cancer includes coughing or shortness of breath, blood cancer, bruising or abnormal bleeding, fatigue and fever.

Types of Caner

Cancer is divided into two types. One type is called benign and the other is called malignant. The growth of benign cancer stops after a certain period of time and does not spread to other parts of the body. However, some benign cancers can also be dangerous. The Malignant tumors are dangerous and have the potential to grow. They can spread to any part of the body.

How Caner Spread?

The process by which cancer spreads from one place to another is called metastasis in medical terms. It is a Greek word meaning to emigrate. The part of the body where the cancer develops is called the primary tumor. For example, if the breast cancer enters any part of the body from its place, but the primary tumor will be called where it has spread from. There are many sources of cancer in the body, such as arteries.

Whether it's clean blood vessels that contain the "oxgyenated" blood or dirty blood vessels that contain "deoxygenated" blood. For example, if colon cancer develops, it first spreads to the liver. This is because one of the blood vessels in the intestine drains into the blood vessels of the liver, through which the cancer reaches the liver. Another source of cancer spread is lymphatic’s.

Lymphatics are actually the body's ducts, which contain water-like material, also called lymph. The function of this lymph is to carry the body's proteins and the substance found between the cells to the blood vessels. These lymph nodes enter the bloodstream through glands in the body and these glands are called lymph nodes. These glands are found at small distances in the body and act as a soldier.

That is, if there are any germs in the lymph, then the white blood cells in these glands are helpful in killing them. Whichever part of the gland appears, the volume of the glands there first begins to increase, which grows into a gland-like shape. As the cancer cells begin to spread throughout the body through the lymphatics, so when they enter the glands, they begin to grow there too and form a lump.

A third source of cancer spread may be that the cancer may spread to other parts of the body to such an extent that it may enter another organ and infect it. As the cancer of the leaf progresses and enters the liver, it also affects it. In addition, cancer cells can spread through the veins (Perineural Invasion).

Cancer and Biopsy

Biopsy is essential for the final diagnosis of any type of cancer. Several methods of biopsy are used. One procedure involves go through to the affected area and examining it with a small tissue microscope. This process is completed in 15 to 20 minutes and the patient does not even need to be admitted to the hospital. Sometimes an incision is made in the gland near the cancer and the entire tumor is removed and examined. This procedure is called Excisional Biopsy.

The second method is punch out, which is done with a special type of needle cut. A small piece of tissue is also removed in a punch-out biopsy. Such a biopsy can be performed with local anesthesia without hospitalization and even after admission to the hospital. And sometimes the patient needs to be completely anesthetized.

However, only a surgeon can decide what will be best for the patient. If the cancer is in the esophagus, stomach or intestines, biopsy is done through endoscopy. Similarly fine needle aspiration cytology (Fine needle). In aspiration cytology, a thin needle is inserted into the affected area to remove the contents, which are usually cans of Thai rye. R is used.

With the help of each type of biopsy tissue, pathologists usually determine the type, and origin of the cancer and how far it has spread in the body. It takes 12 days. A biopsy also makes the final diagnosis of whether it is cancer or a benign tumor. Oncologists recommend treatment methods only after the biopsy report has been given. Keep in mind that biopsy plays a very important role in the treatment of cancer.

Unfortunately, in our society, it is a common misconception that cancer spreads rapidly in the body after biopsy. There is no doubt that cancer cells are very loosely connected to each other, which can spread at the slightest provocation. But the chances of this happening are very low, because according to researchers, thanks to modern technology.

The chances of an outbreak are slim. In 2014, researchers at Raja Rajeshwari Dental College and Hospital, India, after conducting research on cases related to biopsy-related cancer cell seeding from 1983 to 2012, concluded that the risk of cancer spread through biopsy depends on two factors. The first is that some very specific types of cancer are more likely to spread and the second depends on the biopsy method.

However, in most cases, the symptoms of cancer appear only after the cancer has spread in the body. Sometimes, after a biopsy, the report shows that the cancer is not from the place where the tissue was taken, but it has spread to another part of the body. During this time the cancer spreads throughout the body and by the time the biopsy is done, the symptoms start appearing in other parts of the body.

Then it is believed that the cancer has spread after the biopsy. Research done all over the world. It has been proven that cancer does not spread at all through biopsy. According to Dr. Jonathan Appstein, Professor of Pathology, Urology and Oncology at Johns Hopkins Hospital and Director of Surgical Pathology, biopsies do not cause any spread in most types of cancer.

In January 2015, according to a study by researchers in Jacksonville, Florida, patients who underwent biopsy had better outcomes and longer lives than those who did not undergo biopsy. So it is wrong to say that biopsy can spread cancer. It is very difficult for doctors all over the world to treat a cancer patient without a biopsy, but unfortunately most people do not understand this.

That's all there is to it. In addition, the treatment of cancer should not be delayed, because the cancer continues to grow and the more it grows, the more difficult it will be to treat. So it is very imperative to start biopsy in timely manner to performed according to the doctor's instructions, treatment will be quicker. The onset of symptoms may be due to the fact that the cancer is not an incurable disease, provided it is diagnosed early.

Five Foods to Avoid From Cancer



Who isn’t afraid of the word “cancer”? We all know a family member or a friend who had it. And indeed, according to the American Cancer Society, more than one million people in the United States get cancer each year. The American Cancer Society lists many possible causes to cancer disease, including genetic factors, lifestyle factors such as tobacco use, diet, and physical activity, certain types of infections and environmental exposures to different types of chemicals and radiation. Since I’m very interested in healthy nutrition, and foods that are protect against cancer development, but it won’t help if we eat those foods while consuming large amounts of other foods that can increase the risk of cancer. So let’s have a look at these cancer promoting foods so we all know not only what to eat, but what NOT to eat (or at least reduce their intake).

1.      High intake of processed foods
Many diverse substances are adjoined to commercially prepared foods, such as artificial colors, chemical flavors, salt, sugar or artificial sweeteners. These additives are frequently investigated by researchers to check if any of them is thought to be a real risk. Sometimes there is a scare about a particular additive and some additives are thought to be a cancer risk. Heavily salted, smoked and pickled foods, for example, may increase the risk of stomach cancer. This may well explain why there is high rate of stomach cancer in Japan, because salty and pickled foods are very popular. Also an epidemiological study published in June 2010 in the American Journal of Clinical Nutrition observed that a high salt food can increase in 10% risk of stomach cancer. Furthermore artificial food coloring are noticed numerous health risks and research has been is limited to animal studies, including mice and rats, but some claim that these dyes are possibly toxic enough to cause the cancer in the humans.

2. High intakes of red meat, processed meat or charred food
It has been observed the peoples who eat lots of red processed meat can cause bowel and stomach cancer. Red meat includes all fresh, minced and frozen beef, pork, lamb or veal, particularly pork is so injurious for health and leads to cancer.  Therefore processed meats possess a risk of cancer, and these have been preserved in some way other than freezing and include bacon, ham, salami, sausages, corned beef, black pudding, pâté and tinned meat. When you eat processed meats, you are exactly assure consuming sodium nitrite or sodium nitrate, which are added to processed and cured meats to preserve color and extend shelf life. Unluckily, these compounds can be converted to nitrosamine, which is very much famous to cause cancer in laboratory rats (though again, the connection in people is unclear). Also hot dogs, bacon and the like may also be preserved by methods involving smoke or salt, which also increases the exposure to potentially carcinogenic chemicals. Charred food creates chemicals which can damage human cells, and making them more likely to become cancerous. However; it is highly depend on the way you cook your meat can potentially make a big difference in the cancer risk it poses to you. The char-grilled meats that are somewhat burnt on the outside are among the worst foods that increase the risk for cancer.

3. Sugar
There are a number of websites that encourage the idea of sugar “feeds” cancer. They suggest that eating foods with sugar makes cancer breed faster. Due to this some cancer patients avoid eating any sugar, and rejecting beneficial foods, i.e. fruits, that contains vital nutrients. Therefore no decisive research on human subjects to verify that sugar makes cancerous cells grow. Avoiding foods with processed sugar is a decent idea in general, but disregarding foods with natural sugar won’t stop cancer cells from dividing. As per Mayo clinic, sugar doesn’t make cancer grow faster. All cells (including cancer cells) depend on blood sugar (glucose) for instant energy. But giving extra sugar to cancer cells doesn’t speed their growth. Similarly, depriving cancer cells of sugar doesn’t slow their growth. According to Canadian Cancer Society the connection between sugar and cancer is different, eating abundance of sugary foods can cause of rapid gaining weight. Research shows that obese habit or being overweight can increase risk of cancer. Normally obesity may cause changes in hormone levels or insulin that might increase the risk of developing breast, colon or uterine cancer. Thus limiting the sugar level in your diet is really important. High sugar in your diets sugar and refined carbohydrates can lead to overweight and obesity, which indirectly increases cancer risk over time. Sugar can be found several foods such as cookies, sodas, cakes, soft drinks and other sweets even in pasta sauce, salad dressing and canned vegetables. So you’ve to read out food labels carefully, look for sugar e first ingredient and be aware of hidden sugar names: fructose, lactose, sucrose, maltose, glucose, dextrose. Natural sugars such as molasses, honey and maple syrup contain beneficial antioxidants but those, too, should be consumed in moderation.

4.  Fried food, French fries, potato chips and snack food
It is highly important that French fries, potato chips and other snacks you eat, actually may have high levels of acrylamide, another carcinogenic substance that forms when foods are heated at high temperatures, such as during baking or frying. Acrylamide may be gotten in any food heated to a temperature above 250° F, but potato chips & French fries have been observed highest levels of among foods tested. Therefore cooking methods i.e. frying, baking or roasting are more likely to produce acrylamide, whereas boiling, steaming, and microwaving appear less likely to do so. Longer cooking times and cooking at higher temperatures can raise the amount of acrylamide in foods further. It is most important to mentioned here, that the prolonged exposure to acrylamide has caused a range of tumors in animal tests (rats and mice), whereas most of the human studies published so far have failed to find any connection between acrylamide and several types of cancers. Therefore many believe it has a potential to be a human carcinogen because of those animal studies. If you are still worried, the FDA and other public health groups suggest the best way is to follow the general advice on healthy eating, including limiting the consumption of fried and fatty foods. Another component found in these types of foods that may increase the risk for cancers are Trans fats or trans fatty acids. These are formed when manufacturers turn liquid oils into solid fats via a process called hydrogenation.  And indeed, Tran’s fats can be found in many foods including vegetable shortening, margarine, crackers, cereals, candies, baked goods, cookies, granola bars, chips, snack foods, salad dressings, fried foods, fats and many other processed foods. Tran’s fats cannot only increase your risk of cardiovascular disease and two types of diabetes, but the high intake of trans-fatty acids may have a direct association with prostate cancer in men, which ranks number one among the most common malignant cancers in American men. Chronic inflammation plays an important role to the development of prostate cancer and the association of trans-fats and chronic inflammation may explain the link between prostate cancer and trans-fatty acid ingestion. However, further studies and clinical trials are needed to establish this fact.

5. Excess alcohol
Scientific and researchers have strong consensus of the linking between alcohols drinking causing several types of cancer. The peoples who drink alcohol regularly could be high risk of developing an alcohol-related cancer. According to Cancer Research UK and American Cancer society, alcohol can increase the risk of cancers, like as mouth cancer, liver cancer, breast cancer, bowel cancer and throat cancer.  You have perhaps heard about other studies that have found that certain substances in red wine, such as resveratrol, have anti-cancer properties, but like several things in life moderation is the key. The nutrition guidelines suggest physical activity plays a key role for cancer prevention; the people, who drink alcohol, have high risk of cancer.
