Breast Cancer Stages and Survival Rates
Where the disease has not metastasized, the five-year
survival rate for women suffering from breast cancer
is about 86%. That percentage means that 86% of women
who develop breast cancer live for at least five years
after diagnosis. The good news is that depending on
the stage it is discovered, the survival rate can be
even higher than the overall average.
As with most cancers, breast cancer, develops in stages.
A standard classification of letters and numbers is
used to describe the stages - T, N and M and 0-IV. T
depicts tumor size, N signifies a spread to lymph
nodes and M describes distant metastasis.
When a primary tumor spreads to another area/s and forms
more tumors, it has metastasized.
When a tumor cannot be assessed, it is designated
the classification of TX. Where there is no indication
of cancer, T0 is used. If one of the following forms
is suspected - DCIS (ductal carcinoma in situ), LCIS
(lobular carcinoma in situ) or Paget's disease (where
the nipple and/or areola is cancerous) - Tis is used.
Stage 0 indicates that the cancer is in its earliest
stage. Stage I indicates that tumors have not spread
and are less than 2cm in size. A tumor that is 2-5cm
in diameter is classified as Stage II, and a tumor larger
than 5cm is considered Stage III. When a tumor has attached
to the chest wall and spread to the lymph nodes it is
considered to be Stage IV.
Today, due to medical advances, many breast cancers
are diagnosed and treated during the early stages.
Treatment received in Stage 0 and Stage I results in
men and women having five year survival rates of almost
100%. And yes, men can develop breast cancer, though
at a far lower rate of 1/133 when compared to women.
The survival rate for those with Stage II cancer is
between 81%-92%. At Stage III the rate lowers to 67%,
and then drops substantially to 20% at Stage IV.
Despite being a serious condition, breast cancer is
now rarely life threatening. Even sufferers of later
stage cancers often survive past seven years. As technology
and medicine advance, survival rates increase. Even
later stage cancer survival rates are rising as medical
and treatment methods improve.
The QM-MSP (quantitative multiplex methylation-specific
PCR) is one such new method of diagnosis. Discovered
in 2001, it uses fluid from the breast and tests the
chemicals contained in the fluid. The chemical analysis
undertaken during this test allows cancer to be detected
with 86% reliability, and cancer clumps with as little
as 50 cells can found. Treatment given in the early
stages is highly effective, and new methods like this
allow cancer to be diagnosed at the earliest possible
stage.
Treatments are also improving, with hormone therapy,
targeted radiation and molecule specific drugs now readily
available.
Breast cancer is no longer the death sentence it
used to be. While still serious, the odds of beating
this disease are high, and treatments are far less invasive
than in the past.
