Miscellaneous Health Topics

Some items of interest from the world of medicine:

1. Heart Disease:

Heart disease continues to be number one killer. This was recognized in the late 1940s. Since then several risk factors have been identified, including high blood pressure, high cholesterol level and cigarette smoking.

Over the past 30 years, death rate from heart disease has declined by more than 50 percent. This downward trend is continuing. Despite important advances in treatment and prevention, heart disease remains the single most common cause of death in North America.
(The New England Journal of Medicine, September 24, 1998)

2. Alcohol Problems in Canada:

In 1994, 4.1 percent of Canadians had alcohol dependence. Excessive alcohol abuse was a factor in 6701 deaths in this country in 1992. Clearly, alcohol abuse is an important public health issue that needs to be dealt with.

In a recent publication, Poulin and colleagues found that 85 percent of Canadians with alcohol dependence do not seek help, the need for screening and brief interventions is great.
(Canadian Medical Association Journal, Dec 1, 1997)

3. Teenage Girls and Smoking:

Weight control is a major reason that teenage girls take up smoking, according to a study of nearly 3000 British and Canadian school girls.

Girls who smoked were 30 percent more likely to be overweight, were prone to overeat, and were twice as likely to be worried about their body image than non-smokers.

Most smokers also wanted to be considerably thinner than they were and were twice as likely as others to induce vomiting after overeating.
(British Medical Journal, August 8, 1998)

4. Doctors and Religion:

The Medical Post 1997 National Survey of Doctors reveals that 52 percent of physicians consider religion an important part of their life. 26 percent pray outside formal religious services at least once a day. For 13 percent, religious beliefs influence birth control consultations.
(National Survey: the Medical Post 1997 National Survey of Doctors, Fall 1997)

5. Good Health and Multivitamins:

Since the mid-1970s, twenty five percent of American adults have regularly consumed a multivitamin containing 400 micrograms of folic acid. The current evidence suggests that people who take such supplements and their children are healthier.

Consuming a standard multivitamin or a serving of fully fortified breakfast cereal is a convenient, effective, safe, and inexpensive way to increase consumption of folic acid by 400 micrograms of folic acid rapidly.

Prostate Cancer

“Is it my prostate, doc?” Dave asks me at the golf course as he rushes to the washroom for the fifth time.

As a travelling salesman, Dave finds it difficult to make many washrooms stops. He makes an appointment to see me.

Dave is 40. His father has had prostate cancer. Dave wants to know what are his risks and what can he do for prevention and early detection.

The prostate is a small gland, usually weighing about 20 grams. It surrounds the urethra where it joins the bladder. Enlargement of the gland causes voiding problems and may cause bleeding in the urine which may or may not be visible.

Prostate cancer is, after lung cancer, the most common cause of cancer-related death in men. The risk of developing prostate cancer increases with age. At 40, the probability of prostate cancer occurring within five years is 0.01 per cent. At 80, it is eight per cent.

Although the risk is only eight percent, it is important to note that 80 per cent of men at 80 will have prostate cancer. But this will not affect life or life expectancy.

“What’s up doc?” Dave greets me as I enter the examination room.

We discuss symptoms. In a physical examination we find his prostate is slightly enlarged, smooth but quite firm.

There are no hard lumps to cause alarm at this stage.

Although most prostate cancers are diagnosed at 70, they can occur at a younger age. Since Dave has a family history and his prostate is enlarged and firm, he is referred to Urologist for further investigation.

Dave has a blood test – prostate-specific antigen (PSA). This is slightly abnormal. Therefore he has rectal ultrasound and a needle biopsy. This is reported as normal.

“Doc, how often should I have checkups for my prostate?” Dave asks.

His Urologist indicates Dave should have a repeat antigen test in three to six months.

If this is abnormal then he may need a repeat prostate biopsy.

Screening is recommended for men 50 and over. Half the men in this age group develop prostate problems. This may or may not be due to cancer.

Digital rectal examination and antigen tests are recommended for screening high risk patients like Dave. Although neither tests are hundred percent accurate for early diagnoses, they are accepted as part of routine medical checkups.

Dave is happy there is no cancer and his anxiety level improves. He feels reassured about his health.

He is ready to hit the road for another few days of good salesmanship.

Breast Lump

Dave and Susan were anxiously waiting for me.

Since her last visit, Susan has practiced breast self examination. She found a breast lump.

Susan is aware that breast cancer is the most common cancer diagnosed in Alberta women. It also accounts for about 21% of all cancer deaths in women (Breast Cancer – The Picture in Alberta: 1998).

Susan came straight to the point. She told me about her breast lump.

“Dr B, do you think it is cancer?”

“Susan, I will have to do some investigations before I can answer your question.”

I started with clinical history. How long the lump has been present? Has any change been noted? Is there a previous history of breast biopsy or breast cancer?

Age is the most significant risk factor for breast cancer in women. At age thirty, the probability of developing breast cancer in the next five years is 1 in 667. At seventy, it is 1 in 65.

Susan is thirty eight. Her risk is 1 in 208.

Any other risk factors? Susan’s sister had breast cancer. It is estimated that less than 10 percent of all breast cancers have genetic predisposition.

Breast cancer may or may not be painless.

A fine needle aspiration biopsy of the lump was required to establish whether the lump is solid or cystic. A cystic lump has a very low probability of cancer. I also arranged a mammogram. This would provide further information on the nature of the lump. It would also pick up smaller lumps which were not felt during the physical examination.

Susan and Dave were made aware that eighty percent of breast lumps are benign in nature but a breast lump is suspected to be malignant unless proved otherwise.

Within a week I had good news for Susan. The needle biopsy and mammogram did not reveal cancer. She was advised to see me seven to ten days after she starts her next menstrual cycle.

Susan arrived as planned.

I gave her another physical examination to see if the lump had changed or even disappeared. The lump was still there.

Unfortunately, none of the tests we do are hundred percent accurate to rule out cancer.

“Doctor, I know this. I have been talking to my sister. What’s next for me? A surgical biopsy?”

Yes. This would entail a surgical procedure under local or general anesthetic.

Susan underwent day surgery as planned. There was no cancer.

I saw Susan again a few weeks later. She was happy and relieved.

“Doctor, what should I do to stay one step ahead of the game?”

Mammography and physical examination are the mainstay of screening in breast cancer (Cancer Screening in 1995; Current Oncology; March 1995).

Susan got ready to leave. I gave her some pamphlets to read.

“Call me if you have any questions,” I said as Susan stepped out of the door.

She smiled and said, “Thank you, doctor!”

Screening Tests for Cancer Prevention

I was expecting a visit from Susan.

My imaginary friend, patient and Susan’s husband, Dave, had warned me about this a few days ago.

Susan wanted to know how screening tests can prevent cancer.

Susan had good reasons to worry about cancer. Her sister had surgery for breast cancer. Her mother has had colon cancer. Susan’s recent pap smear was abnormal.

Susan is thirty eight years old. Weighs 130lbs. She is five feet seven.

She is very athletic. Plays squash and racquetball. Jogs regularly.

Does not smoke and drinks alcohol socially.

Susan works as legal secretary and has two children.

Susan is a fine example of a healthy person. Can anything go wrong with her health?

Unfortunately, yes!

“Hello Dr B, I hope you are having a good day today!” Susan greeted me as I entered the examination room.

“Yes, Susan, I am having a wonderful day.”

I was running on time. I didn’t have to give any bad news to patients that day. Sun was shining and I was looking forward to a relaxing evening with my family.

Unlike Dave, Susan likes to call me Dr B or doctor. I have never heard her say “What’s up doc?”

Without wasting any time, Susan came straight to the point: “Doctor, what are my risks of developing cancer?”

“Cancer will develop in 1 in 3 Albertans during their lifetime” says the Alberta Cancer Board document, A Snapshot of Cancer in Alberta (1996).

“What about my family history, doctor? That does put me at a higher risk than other Albertans. Surely, I need to be more careful.”

Yes, Susan is right. Unfortunately, we are all at the mercy of our genes.

“Doctor, is there a difference how cancer affects men compared to females?”

Yes, men outnumber women in total numbers of cancers and deaths related to cancer.

It is also important to remember that there is a high level of premature deaths from cancer among women than men. Some of the cancers affecting women tend to occur at a younger age, says the Alberta Cancer Board document.

“Dr B, what are the top five cancers which kill Alberta women?”

Breast cancer tops the list. This is followed by lung, colon and rectum, unknown primary (original site of cancer cannot be found) and pancreas.

“What about men?”

Lung, prostate, colon and rectum, stomach and pancreas in that order.

“Doctor, what about cancer of the cervix?”

Cancer of the cervix has been decreasing among Canadian women. This is most likely due to the widespread use of pap smear, says the Cancer Board document.

“Dr B, what sort of screening tests would you recommend for me and Dave?”

Cancer screening in 1995 is an interesting article (Current Oncology -March 1995) written by Dr B. P. Higgins. He mentions five tumor sites where screening has been recommended.

“What are these sites, doctor?”

Prostate, breast, colon and rectum, ovary and cervix.

Susan looked at her watch. It was time to pick up Andrew and Tamara from school.

“Dr B, can I bring along Dave next time so we can go through this together?”

“Sure, Susan. I would be happy to sit down and discuss this with both of you.”

Susan stepped out of the examining room. After a couple of steps, she turned back and whispered,” Doctor, do know what Dave said the other day?”

“What did he say?” I asked. She smiled. I asked again, “Susan, what did he say?” Curiosity was killing me.

“He said that trying to stay healthy was more difficult than ………improving his golf game!”

I was having a wonderful day and I wasn’t going to spoil it by talking about golf. Golf…..who invented that game?
