Breast Cancer – Causes,
Signs and Symptoms, Diagnosis, Treatment and
Prevention
Breast cancer is the most common
cancer in women affecting one in eight women during their
lives.
It may develop at any time but the risk of developing it
increases as women get older. It is far more common
in post-menopausal women and the risk continues to
increase with rising age.
CAUSES OF BREAST CANCER
The cause of breast cancer is not
known but while it can also occur in men, the much higher
occurrence in women implicates estrogen.
Today, breast cancer, like other forms of
cancer, is considered to be the final outcome of multiple
environmental and hereditary factors. Breathing secondhand smoke
increases breast cancer risk by 70% in younger, primarily
pre-menopausal women.
A newly released study indicates a
correlation between the drop in breast cancer and the
drop in women taking HRT.
SIGNS AND SYMPTOMS
Breast tumors elicit so many fears,
including those relating to surgery, death, loss of body
image and loss of sexuality, however they more easily
treated and often curable if the tumour is found early,
therefore regular self examination and screening is
essential. Breast cancer usually shows as a lump or
thickening in the breast tissue, although most breast lumps
are not cancerous.
Certain predisposing factors are
clear.
Women at high risk are those
who:
Have a family history of breast
cancer.
Have long menstrual cycles, began
menses early or menopause late.
Have never been
pregnant
Were first pregnant after age
31.
Have had unilateral breast
cancer.
Have endometrial or Ovarian
cancer.
Were exposed to low level ionizing
radiation.
Many other possible factors are
still under investigation including, obesity, alcohol and
environmental factors.
Those with lower risk include
women who:
Were pregnant before age
20.
Have had multiple
pregnancies.
Are native American or
Asian.
Breast carcinomas occurs more
often in the left breast and in the upper
quadrant.
Indications of breast cancer other than a
lump may include changes in breast size or shape, skin
dimpling, nipple inversion, or spontaneous single-nipple
discharge.
TYPES OF BREAST CANCER
When breast cancer cells invade
the dermal lymphatics, small lymph vessels in the skin of
the breast, its presentation can resemble skin
inflammation and thus is known as inflammatory breast
cancer (IBC). Symptoms of
inflammatory breast cancer include pain, swelling, warmth
and redness throughout the breast, as well as an orange
peel texture to the skin referred to as peau
d'orange.
The most common pathologic types
of breast cancer are invasive ductal carcinoma, malignant
cancer in the breast's ducts, and invasive lobular
carcinoma, malignant cancer in the breast's
lobules.
Occasionally, breast cancer
presents as metastatic disease, that is, cancer that has
spread beyond the original organ. Bone or joint pains can
sometimes be manifestations of metastatic breast cancer,
as can jaundice or neurological symptoms.
TREATMENT
Much controversy still exists over
treatment of breast cancer, options include; Surgery ,
chemotherapy, Radiotherapy,Hormonal therapies,Herceptin
and complementary treatments.
The mainstay of breast cancer treatment is
surgery when the tumor is localized, with possible adjuvant
hormonal therapy (with tamoxifen or an aromatase inhibitor),
chemotherapy, and/or radiotherapy.
In February 2007, the MammaPrint
test became the first breast cancer predictor to win
formal approval from the Food and Drug
Administration. This is a new gene test
to help predict whether women with early-stage breast
cancer will relapse in 5 or 10 years, this could help
influence how aggressively the initial tumor is
treated.
Interstitial laser thermotherapy
(ILT) is an innovative method of treating breast cancer
in a minimally invasive manner and without the need for
surgical removal, and with the absence of any adverse
effect on the health and survival of the patient during
intermediate followup.
PREVENTION
Routine (annual) mammography of women
older than age 40 or 50 is recommended by numerous
organizations as a screening method to diagnose early breast
cancer and has demonstrated a protective effect in multiple
clinical trials.
Women with one or more
first-degree relatives (mother, sister, daughter) with
premenopausal breast cancer should begin screening at an
earlier age.
PROGNOSIS
There are many prognostic factors
associated with breast cancer: staging, tumour size and
location, grade, whether disease is systemic (has
metastasized, or traveled to other parts of the body),
recurrence of the disease, and age of
patient.
With advances in screening, diagnosis, and
treatment, the death rate for breast cancer has declined by
about 20% over the past decade, and research is ongoing to
develop even more effective screening and treatment
programs.
