Tumor Cells

The cancer tumor cells are those abnormal cells that divide uncontrollable and invade other tissue. The blood and the lymph systems are the ways on which cancer cells spread to other parts of the body. Cancerous cells may affect almost every organ or tissue in the body and they are named by the organ where they appear. There are over 100 different types of cancer.

Here are some of the most common types of cancer:
• Carcinoma is the type of cancer that starts in the skin or tissues on the internal organs;
• Sarcoma occurs in the bones, cartilage, fat or muscles and blood vessels;
• Leukemia is a common type of cancer, difficult to cure in most cases. It begins in the blood-forming tissue such as the bone marrow. The leukemic cancerous cells spread very easily through blood;
• Lymphoma is the cancer of the immune system’s cells;
• Central nervous system cancers happen in tissues of the brain or spinal cord. Read more…

Kidney tumors cells can be cancerous or non-cancerous. Tumor on kidney that is benign is not life threatening and normally does not show any symptoms. The benign renal tumors are usually found incidentally because they are asymptomatic.

The most common form of tumor on kidney is the renal adenoma. It is a benign tumor with no particular cause known. They are quite small and solid and they look like growths. Whereas renal adenomas do not seem to be dangerous for those who have them, in rare cases they may affect the functions of the kidney because they grow too large. Usually they are asymptomatic but once they grow large patients may experience symptoms similar to renal cell carcinoma symptoms.

Renal cell carcinoma or RCC is the most common type of kidney cancer tumor in adults. Its prevalence is up to 80% of patients with kidney cancer. RCC begins in the cells in the lining of the proximal convoluted tubule. It is also the most lethal type of cancer that affects the kidney and the patients do not usually live more than 5 years after the condition was diagnosed and staged. Read more…

Liver tumor cells are cells that form abnormal masses of tissue because they reproduce at a very high speed. If the cells are cancerous then the liver grows a malignant or cancerous tumor, while non-cancerous, normal cells develop a benign tumor.

It is very important that patients should know that most liver cancerous tumor start in other parts of the body, that is why medical screenings should be made for the entire body, not just one organ. Also, most benign tumors are discovered by accident when the imaging test is done for another reason. A non-cancerous or benign tumor is very common in many patients and it doesn’t produce symptoms. It is usually discovered with an ultrasound, magnetic resonance imaging (MRI) or computed tomography (CT) scan.

The most common types of benign liver tumors are the hepatocellular adenoma and the hemangioma. The hepatocellular adenoma develops in women of childbearing age and may require surgery if they rupture and bleed in the body. They rarely develop into cancerous tumors. The hemangioma is very common, almost 5% of adults have small hemangiomas that cause no symptom at all. A cancer liver tumor or malignant tumor can be originated from the liver, meaning that it developed in the liver first and in this case it is called a primary liver cancerous tumor. If the tumor spreads out from the cancer to some other place in the body, it means that the patient is developing metastatic liver cancer. Read more…

There are several types of lung tumor cells. Some lung cancers occur in the center of the chest and others occur in the periphery. The majority of cancer lung tumor growths in the early stage are not visible on a chest x ray. By the time a cancer is visible on a chest x ray, it is at least the size of a “quarter”. Why cancer lung tumor occurs is not well understood. The biggest risk factor for lung cancer is smoking. However, even among those who smoke, lung cancer only occurs in about 10% of individuals. Other risk factors for lung cancer include radon and asbestosis exposure, and second hand smoke. Lung carcinoid tumors have no association with smoking.

In most cases, lung cancers do not cause symptoms in the early stage. The symptoms of lung cancer also depend where in the lung the tumor is growing. Some individuals may develop a dry persistent cough or a change in cough intensity. Others may develop varying degree of shortness of breath and there may even be streaks of blood in the coughed up sputum. Chest pain or a vague ache may occur and be associated with wheezing, hoarseness and generalized bone pain. With time, most people develop weight loss. Read more…

Tumors can be classified in benign and malignant tumors. While a benign tumor is non-lethal and has a slow grow rate, malignant tumors are cancerous masses that expand very quickly and, because of their high metastasize rate, they can spread to other areas of the body, causing cancer to develop in those areas too.

The malignant cells are different than normal body cells. Normal body cells have a regular shape, while cancerous tumor cells are irregular and contain large irregular chromatin and nucleoli. Malignant cells also act different than normal cells, because they don’t stick together like normal ones do. When observed under a microscope, they stain differently.

Symptoms for a malignant cancerous tumor can vary depending on the area of the body where the cancerous tumor is located. Some patients with malignant tumors may not experience any symptom until the cancerous tumor reaches its most aggressive stage. That is why monthly body tests and screenings are required. Signs for malignant tumors located in the colon may include diarrhea, constipation, anemia and bleeding, while a cancerous tumor developed in lungs are accompanied by shortness of breath, chest pain and coughing or coughing with blood. General malignant tumor symptoms include fatigue, fever, pain, loss of appetite and weight loss. A malignant breast tumor is felt as a very hard bump, like a bit of raw carrot. It has an irregular shape and because it doesn’t necessarily move during a manual breast exam, it is very hard to tell if the tissue and the skins are moving, or if the tumor is moving. Read more…

The MIRACLE project (Magnetic Isolation and molecular analysis of unmarried disseminated and circulating tumor cells on chip), is a thinking formed by groups of researchers and industrial operators crossways Europe united to beat cancer. The European Union has funded this project with the goal of developing a system LOC (Lab – on-a – chip) which intends ” level to the goal: a system that is automated and programmed to detect tumor cells disseminated and circulating. With this system you shall have a cancer diagnosis faster and safer.

To date, the research teams have worked and are working to discover treatments and cures for new methods to beat primary tumor in the initial place. Unluckily, regardless chemotherapy treatments, primary tumor cells can survive and spread to other parts of our body, causing the development of so-called metastasis or secondary tumors.
For these cells known “occult “can go unnoticed for numerous diagnostic tests and spread to other areas through blood flow. Thanks to the project MIRACLE, these cells “hidden “can be recognized and go behind as both therapy and what happens to pathology. Presently, analysis of tumor cell detection is performed merely in costly medical laboratories, which take a long time (about 24 hours) to analyze and monitor them.

Thanks to the project MIRACLE such analysis shall be conducted in a faster and less costly. The project, led by the Interuniversity Microelectronics middle (IMEC) in Belgium, shall use electrochemical sensors to detect cancer cells before, and to extract their genetic stuff then, in a manner that shall amplify the markers to beat cancer. With this new project shall have a new cancer diagnostics and treatments tailored?

“Fight cancer”, “Beat cancer” are very popular expressions these days, and it is good so. Although October, the Breast Cancer Awareness Month is over, one can still see many people wearing pink ribbons on their jackets, which is a demonstration of their will to help those women who suffer from this disease. And this is very much appreciated and should be acknowledged. Fundraising and information events, websites, donations, merchandise, advertisements all over the media, groups on social networking sites, individuals spreading the word – attention is certainly given to the subject and considerable amount of money is collected.
However, looking a little bit closer, as a cancer survivor myself who studied the subject from the most various resources available for public, I personally have some questions, doubts and reservations about these research programs and might be a bad person, but I did not donate one single cent and not intend to do so. Tell you why.
Fight. A key word when talking about cancer.
How do you best fight so that you win? You know your enemy.
A problem – any problem – can be only handled if one knows the exact cause of it. This should be clear – how else do you solve a situation, if you don’t know what is it exactly?
Let’s take breast cancer, it looks like this: each year $ millions are spent to find out the causes of cancer AND more importantly, develop new treatments. Let me suggest: treatments can be only effective when they target the root of the problem… “The exact causes of breast cancer are not known.” In fact, according to the publicly available statements, causes of cancer are a mystery for the medical profession.

In addition to ‘treatment directed’ research such as finding chemicals that effect cancer cells, basic research continues apace, into differences between normal and cancerous cells. In the last 30 years this research has revealed much about our nature, but still no cure. Below are some current strands of scientific research into cancer.
Antibody-guided therapy: this is the original ‘magic bullet’. Cancer researchers use monoclonal antibodies to carry poisons directly to the cancer cells without harming others.
Chronobiology: much of what happens in our bodies is governed by cycles, from the female monthly cycle to the cycles of brainwaves. Human health depends on interacting cycles geared to acts of perception, breathing, reproduction and renewal. Chronobiology analyses these cycles in relation to different times, such as day and night. Hormones, including stress and growth hormones, have their own cycles. For example they may be at their highest activity in the morning and quieter at night. Cancer cells seem to no longer obey the same cycle rates as normal cells.
Anti-telomerase: one part of a cell, called the telomerase, governs the life cycle of a cell and how many times it may multiply. Some cancer cells escape this control and can increase the number of times they divide, becoming ‘immortal’. Researchers hope to gain control over cancer cells by stopping the action of telomerase.
Anti-angiogenesis: secondary tumours (metastasis) can persuade the cells around them to grow new blood vessels to feed the tumours, supplying oxygen and nutrients for the growing cancer. This process is called angiogenesis and research here is finding ways to stop the signals to normal cells that start the process. Read more…

Studies on whey demonstrate it’s an even better protein supplement than previously thought. Although whey protein’s health benefits have only recently been elucidated, the use of whey protein for medicinal purposes has been prescribed since the time of Hippocrates. In fact, there are two ancient proverbs from the Italian city of Florence that say, “If you want to live a healthy and active life, drink whey,” and, “If everyone were raised on whey, doctors would be bankrupt.”
In previous issues, we’ve chronicled the extensive research showing the many potential health benefits of whey protein concentrate. The majority of that research was done in the 1980s and early 1990s, and was extremely persuasive. Scientists have continued their research on whey proteins with even more impressive results. What follows is some of the more current, interesting and useful research on whey proteins.
Whey and Cancer
Additional studies have been done on animals regarding cancer-causing chemicals to see what effects whey protein concentrate would have on cancer prevention or treatment. Scientists fed rats various proteins and then subjected them to the powerful carcinogen dimethylhydrazine.
1.As with the previous research, the rats fed whey protein concentrate showed fewer tumors and a reduced pooled area of tumors (tumor mass index). The researchers found whey protein offered “considerable protection to the host” over that of other proteins, including soy.
2.Even more exciting, in vivo research on cancer and whey showed whey protein concentrate inhibited the growth of breast cancer cells at low concentrations (Baruchel S. and Vaiu G., Anti Cancer Research, 1996). Finally, and most importantly, a fairly recent clinical study with cancer patients showed a regression in some patient’s tumors when fed whey protein concentrate at 30 grams per day. Read more…

The intransigent, self serving, close mindedness of some members of organized medicine is being shattered by sharp truths fired by scientists

from all over the country. It is becoming embarrassingly clear to the big “Cancer Research” organizations, that no matter how many guinea pig volunteers at U.S. penitentiaries they inoculate with liver cancer cells, the subjects do not get cancer. No matter how much time is wasted repeating this experiment and how much public money is spent in a benighted effort to square a circle, the luster of the words, “There is no cancer in normal metabolism,” grows brighter.

This viewpoint is no longer as controversial as it once was. Today, a doctor from the Mayo Clinic and Mayo Foundation can tell the board of trustees of the Allergy Foundation that allergy is believed to be closely related to the natural process of i

mmunity, which include the body’s production of antibodies to combat invasion by germs, and that evidence of many kinds has shown that factors in the body’s resistance are associated closely with the inception and subsequent course of human cancer. Theorists have suggested that cancer cells may develop from time to time in the normal body, but that most of these are sufficiently abnormal to be attacked successfully by the body’s natural defenses.

Today, it is becoming increasingly difficult to deny the role of the liver in cancer, especially since the discovery of the TIP – Tumor Inhibitory Principle – which is manufactured by this organ. The normal liver produces a chemical factor that powerfully inhibits growth of experimental cancer in mice. The factor is imparted both to the blood serum and to the bile and has not been found in cancer patients. The evidence suggests the hypothesis that deficiency, either hereditary or acquired, of such inhibitory factors might be fundamental to the cause of cancer. Read more…
