BREAST CANCER: What To Hope, How To Cope.
BREAST CANCER: What To Hope, How To Cope.
Rita had none of the classic risk
factors. She was 40 years old, healthy, and had no family history of breast
cancer. Her regular mammogram had shown nothing abnormal. But one day while
examining her breast in the shower, she felt a lump. It turned out to be
cancer. Rita and her husband sat numbly while the doctor explained her options.
In times past, a doctor would
tell a woman with breast cancer that her only hope lay in a radical mastectomy
–a disfiguring operation that removed the breast, lymph nodes in the chest and
armpit, and chest muscles. Chemotherapy or radiation treatments often prolonged
the ordeal. Understandably, many dreaded the ‘cure’ more than the disease.
The battle against breast cancer
has been an going struggle between the need to treat a killer aggressively and
the desire to avoid needless disfigurement and painful side effects. Like Rita,
today’s breast cancer patients may have a range of treatment options. And a steady
stream of medical studies and media reports hold out hope that breakthrough
treatments, predictive tests, and protective diets will finally conquer the
disease.
Despite medical advances,
however, breast cancer remains a leading cause of female cancer death. The
industrialized countries of North America and Western Europe have high
incidences of cancer, but numbers are rising in Asia and Africa, which have
historically had lower incidences.
Moreover, death rates among those
diagnosed in Asia and Africa are higher. Why? “Early detection is negligible,”
said a doctor in Africa. “Most patients come to us when they are already in an
advanced state.”
Risk increases with age. Some 80
percent of cases are in women over 50. But the good news is that breast cancer
is one of the most treatable cancers. Indeed, 97 percent of women whose
early-stage breast cancer is localized are still alive five years after diagnosis;
Rita recently passed the five-year mark.
BREAST CANCER BASICS
As in Rita’s case, breast cancer
is often detected as a strange lump. Fortunately, though, about 80 percent of
such lumps are benign, or self-contained, many simply being fluid-filled sacks
called CYSTS.
Breast cancer begins with a
renegade cell that divides uncontrollably, gradually forming a tumor. A tumor
turns malignant, or cancerous, when its cells invade other tissues. Some tumors
grow quickly; others may take up to ten years before they are detected.
To test Rita for cancer, her
doctor used a thin needle to take a tissue sample from the lump. It contained
cancer cells. So she had surgery to remove the tumor and the surrounding breast
tissue and to determine the tumor’s stage [size, type, and spread] and grade
[speed of growth].
After surgery, many patients have
additional treatments aimed at preventing the recurrence or spread of the
cancer. Cancer cells can break away from a tumor, travel through the
bloodstream or the lymphatic system, and start growing again. The spread, or
metastasis, of cancer to vital organs and tissues –the brain, the liver, the
bone marrow, or the lungs –is what turns the disease deadly.
Rita underwent both radiation and chemotherapy
to destroy stray cancer cells around the original site and throughout her body.
Since her form of cancer fed on estrogen, she also underwent antihormonal
therapy to hinder the growth of new cancers.
Advances in breast cancer
treatment offer other options to patients according to their age, health,
cancer history, and the individual cancer. For instance, in the case of a woman
named Lizzy, tests revealed her cancer before it spread beyond the milk duct.
So she had a lumpectomy, which saved her breast.
Alice had chemotherapy before
surgery to shrink her tumor. Janice’s surgeon removed the tumor and only the
sentinel lymph node, the first node into which the fluid from the tumor drains.
Since it had no cancer cells, additional nodes were left intact. This reduced
Janice’s risk of lymphedema, an uncomfortable swelling of the arm that can
occur when many lymph nodes are removed.
Much is known about the growth of
breast cancer, but a basic question continues. Why and how does breast cancer
start?
THE CAUSES ?
The causes of breast cancer
remain a puzzle. Critics say that more research is done on treatment and
screening –which reap big profits –than on causes and prevention. Still,
scientists have unearthed important clues.
Some believe that breast cancer
results from a complex, multistep process, beginning with a faulty gene that
causes cells to misbehave –to divide furiously, to invade other tissue, to
evade capture by immune cells, and to launch stealthy attacks on vital organs.
Where do errant genes comes from?
In between 5 and 10 percent of cases, women are born with genes that predispose
them to breast cancer. But it seems that in many cases, healthy genes are
damaged by outside agents –radiation and chemicals being among the prime
suspects. Future studies may confirm these links.
Another link includes the hormone
estrogen, which appears to stimulate certain breast cancers. Hence, a woman’s
risk may be raised if she began menstruating very early in life or went into
menopause later than normal, if she had a late first pregnancy or no pregnancy
at all, or if she had hormone replacement therapy.
Because fat cells produce
estrogen, obesity may increase risk in postmenopausal women, whose ovaries have
stopped producing hormones. Other risk factors include high levels of the
hormone insulin and low levels of the sleep hormone melatonin, a condition
often affecting night workers.
Are more-effective,
less-traumatic treatments for breast cancer on the horizon? Researchers are
developing therapies that involve using the body’s own immune system and drugs
that target the molecular pathways that support cancer growth. Meanwhile,
improved imaging technologies should help clinicians deliver radiation more
precisely and effectively.
Scientists are also fighting on
other fronts, including unlocking the mystery of metastasis, outwitting
chemoresistant cancer cells, disrupting cellular-growth signals, and tailoring
treatment to individual tumors.
SIGNS TO WATCH FOR
Early detection is crucial, but
some studies caution that breast exams and mammograms may be less accurate in
younger women, resulting in unnecessary treatment and anxiety. However, experts
strongly urge women to watch for changes in their breasts and lymph nodes.
Here are some signs to watch for:
1. A
lump or thickening anywhere in the armpit or breast
2. Any
discharge other than breast milk from the nipple
3. Any
change in the color or texture of the skin
4. An
abnormal pushed-in or tender nipples
COPING WITH SIDE EFFECTS
Side effects of
some cancer treatments may include nausea, hair loss, chronic tiredness, pain,
numbness or tingling in extremities, and skin reactions. The following simple
steps may reduce such effects:
1.
Eat well to strengthen your immune system.
2.
Keep a log of your energy levels and your
reactions to foods.
3.
See if medication, acupuncture, or massage
lessens nausea and pain.
4.
Exercise moderately to increase your stamina,
control your weight, and improve your immune response.
5.
Rest often, but be aware that long periods in bed
may increase fatigue.
6.
Keep your skin moist. Wear loose clothing bath
in warm water.
