Brain Cancer


What is Brain Cancer?

Brain cancer is a disease in which cancer cells are found in the brain

Types of Brain Tumors

There are two types of brain tumors: primary brain tumors and metastatic (secondary) brain tumors.

Primary brain tumors originate in the brain. Primary brain tumors can be cancerous or noncancerous. Both types take up space in the brain and may cause serious symptoms. The most common symptoms and complications are vision loss, hearing loss and stroke. A noncancerous primary brain tumor is life threatening when it compromises vital structures.

Metastatic (secondary) brain tumors are brain tumors that that originate from cancer cells that have spread from other parts of the body.

Types of Brain Cancer

Primary brain cancer rarely spreads beyond the central nervous system. Death from primary brain cancer is a result of uncontrolled tumor growth within the limited space of the skull.

Metastatic brain cancer indicates advanced cancer and has a poor prognosis.

All cancerous brain tumors are life threatening (malignant) because they have an aggressive and invasive nature.

What Causes Brain Cancer?

Exposure to vinyl chloride is known to cause brain cancer. Vinyl chloride is a toxic chemical compound frequently used in manufacturing. It is a combustible, colorless gas. Vinyl chloride is also known as chloroethene, chloroethylene, and ethylene monochloride. A known human carcinogen, vinyl chloride can cause live cancer, angiosarcoma, and other health problems in people who are exposed to it.

People are exposed to vinyl chloride by either breathing in air containing vinyl chloride or consuming water contaminated with it.

Other Causes of Brain Cancer

Genetic mutations and inherited diseases that are associated with brain tumors include the following:

  • pituitary adenoma
  • patients with a history of melanoma, lung, breast, colon, or kidney cancer

Symptoms of Brain Tumors

There are many symptoms of brain tumors. The symptoms will depend on the part of the brain the tumor is located. The most common symptoms of brain tumors are:

  • nausea
  • vomiting
  • headaches
  • behavioral and emotional changes
  • impaired judgment
  • loss of hearing
  • impaired sense of smell
  • memory loss
  • seizures
  • muscle weakness
  • paralysis on one side of the body
  • reduced mental capacity
  • vision loss

Treatment options for Brain Cancer

Brain cancer can be treated. The kinds of treatment used will depend on the age of the patient, the stage of the disease, the type and location of the tumor, and whether the cancer is a primary tumor or brain metastases.

Treatment usually involves any combination of surgery, radiation, and chemoteraphy

Ignoring the Root Causes of Obesity


ABC news among other news sources today is reporting that obese patients incur 43% higher medical costs than non-obese patients, and overall obesity-related medical conditions account for 9% of all medical spending. Their source is a CDC study. The study's lead author, Eric Finkelstein, is quoted by ABC as saying, "Although societal changes are necessary, physicians can play a role in curbing the obesity epidemic by talking to their patients about weight loss in a clear manner so the patient really understands their health risks."

In this manner, by treating the issue as one primarily of proper patient education, Finkelstein actually perpetuates a long-hidden problem, which I will dare to put forward here. Put aside for a moment research which suggests that obesity may have genetic properties. Put aside all the diet plans, the weight watcher plans, the Atkins Diet, Jenny Craig, etc., etc. Put aside everything you thought you knew about obesity. Put it all aside, and consider something different for one moment.

Is it possible that obesity has a much more sinister root, one which gets almost no attention? The answer is a resounding yes. That root which it likely shares with many other medical problems and has eight contributing "branch roots" that combine together to cause problems for people: (1) patient physically abused, (2) patient verbally abused, (3) patient sexually abused, (4) a family member in prison, (5) mother physically abused, (6) a family member with a drug or alcohol problem, (7) a parent was missing, and (8) where someone in the family was chronically depressed, mentally ill or suicidal.

These factors were measured in a study instigated by another study originated by Dr. Vincent Felitti, then chief of Kaiser Permanente's Department of Preventive Medicine in San Diego., as reported by Jane Ellen Stevens in the Sacramento Bee, July 31, 2005. He released the results of his seminal study in 1990, and those results received widespread rebuff and pooh-poohing by his peers in the medical community. He developed the study to figure out why obese patients, even those successfully losing weight, so often leave whatever program they're succeeding with and revert to their previous, high weight levels.

The study began with a simple patient medical questionnaire in which Dr. Felitti asked a respondent the wrong question. He intended to ask, "How old were you when you were first sexually active." Instead, he misspoke and asked, "How much did you weigh when you were first sexually active?"

The answer he got was, "40 pounds."

Stevens wrote, "He thought he'd misheard. He asked again. She gave the same answer, began sobbing, and added: 'It was with my father.'"

It was the first instance of sexual abuse he had heard of in 23 years in practice. About 10 days later, he got a similar response from another interview. Pretty soon, he began to ask more pointed questions in this regard, and started getting consistent responses that talked about sexual abuse in the respondent's background.

Concerned that his own bias might be causing the unusual response rate, he asked five medical colleagues to do the next 100 surveys. The results remained the same. They found a staggering amount of sexual abuse among the obese patients he surveyed.

No wonder his medical colleagues rejected his conclusions when he submitted the results of his survey! They simply refused to believe his claims. On the other hand, "Felitti began to realize that obese people didn't see their fat as a problem. For many, it was a solution."

He later received CDC assistance with a related study that found that when at least four of the eight factors I listed above appeared in a person's personal history, the person was also 390% more likely to be a smoker (and 390% more likely to have pulmonary lung disease), 240% more likely to suffer from hepatitis, 250% more likely to have a sexually transmitted disease, 460% more likely to be suffering from depression, and 1220% more likely to have attempted suicide.

Those people with six out of eight factors in their personal background had a "4600% increase in the likelihood of becoming an IV drug user. Most startling of all: 64% of the study participants had experienced one or more categories of adverse childhood experiences."

The results of this survey were presented in 1999, and as I said, the survey was conducted by the CDC.

So here's the question: why is the CDC's most recent study pushing this information aside when it conducts its current study? Why is it concentrating on physicians presenting medical risk information properly to obese patients, rather than focusing on the abusive histories of obese people? The answer is very simple. The CDC can do nothing about root causes of obesity. So, to continue to justify their funding, they concentrate on what they can influence: physicians.

This excellent example clearly illustrates government incompetence and impotence when it comes to solving "social problems" which it so loves to address. It can't do anything about the fact that so many people are likely overweight because of their personal histories of abuse, so they push it aside.

Unfortunately, the rest of society tends to follow the government's (and the CDC's) lead. The result is that almost no one pays any attention to root causes. Instead, most experts focus on addressing symptoms.

The truly ironic thing is that government actually could do something in this case. They could use their immense bully pulpit to start trumpeting the incidence of sexual, physical, and verbal abuse in causing later medical problems. Of course, to do this they'd have to abandon the idea that they can lead significant change in these issues. It would mean changing emphasis to an individually-based approach to solving these problems, rather than a governmental approach. This is why the CDC and the Federal government will never take this approach.

The irony is astonishing. The lesson is one to be remembered by all who advocate greater government involvement in health care. Governmental involvement will likely make the overall health care situation much, much worse by ignoring the fact that government is actually powerless to achieve positive, productive improvement in health care.

H1N1 cases cross the 1,000 mark

The new virus was first detected in people in the U.S. in April 2009. The virus spreads from person to person in much the same way as seasonal influenza viruses.

The symptoms of H1N1 flu

  • fever of more than 100 degrees Fahrenheit
  • cough
  • sore throat
  • muscle aches
  • headache
  • chills
  • fatigue
  • diarrhea (not common)
  • vomiting (not common)

Until today, H1N1 cases breached the 1,000 mark when 55 new cases were reported nationwide today, said Director-General of Health Tan Sri Dr Ismail Merican.

He said of the new cases, 43 were from seven new clusters, five from existing clusters, six isolated cases and one imported case.

“To date, 1,075 cases have been recorded with one death. Of the number 574 cases (53 per cent) are imported cases while 501 cases (47 per cent) involve local transmissions. However, only four cases, or one per cent, were receiving anti-viral treatment at hospitals,” he said in a statement here.

In relation to this, he said the ministry would continue to monitor cases of H1N1 or influenza-like illness (ILI) being treated in hospitals. Ismail urged the public to report to the Health Department should they be aware of those around them showing symptoms of H1N1 or ILI.

“Those who show heavy symptoms or are at high-risk must seek immediate treatment at the nearest hospital,” he said.

“For lighter cases, they can simply get rest at home but always practise good personal hygiene and make sure their surroundings are clean as well as wear masks. If conditions worsen they must seek medical treatment,” he said.

Regarding reduced attendance because of fever and flu in schools and at the workplace, Dr Ismail said the matter must be reported immediately to the nearest District Health Office.

“As for students in schools and institutions affected by temporary closure, only those who are free from signs of H1N1 and ILI will be allowed to return.

“However, those who still show signs of the disease are advised to continue resting because they are at risk of spreading the virus to their friends,” he said. — Bernama
