What are the signs and symptoms of Breast Cancer?
There are several common and some distinct signs that are seen when breast cancer develops.
The signs and symptoms of cancer include:
-
Lump in breasts
-
Change in size/shape/appearance of breast
-
Change/new dimple on breast skin
-
Recently inverted nipple
-
Peeling/flaking of skin around nipple (areola)
-
Redness over breast skin
The cause for the development of cancer is yet unknown however, when the
cancer affects the breast it results in abnormal development of breast
tissue cells. The cancer-affected cells in the breast begin to multiply
faster and uncontrolled which then begin to form lumps (tumorous
growths). The cancer is also known to spread (metastasize) to the other
surrounding tissue and organs, including the lymph nodes.
Breast
cancer is mostly seen beginning in the tissue cells of the
milk-producing ducts (also known as invasive ductal carcinoma) or it may
begin in the lobules (invasive lobular carcinoma) as well as any other
part of the breast.
How is Breast Cancer diagnosed?
It is treated successfully when it is diagnosed sooner and treated
accordingly. These are some of the best and most common diagnosis tests
for detecting breast cancer:
Breast examination – This
is a physical examination of the breasts that lets the doctor check the
breast tissue for lumps. The doctor will check the breasts and the
lymph nodes in the armpit for abnormalities.
Mammogram – This is an x-ray imaging test for the breasts. These are very useful in seeing any abnormal growth in the breast tissue.
Ultrasound – Ultrasound
test uses high-frequency sound waves to produce detailed of the
internal structure within the breast. This test will effectively
highlight any type of abnormal lump or mass in the breast.
Biopsy – The
surgeon will use minimally invasive surgical method to remove a small
portion of the suspected cancerous tissue from within the breast. This
breast tissue sample is then sent to a pathology laboratory for detailed
analysis.
Breast MRI – The breast magnetic
resonance imaging (MRI) is an advanced diagnostic imaging test. It uses
powerful magnets and radio waves to create a significantly detailed
cross-sectional image of the breast tissue. A contrast dye is often
injected before the breast MRI to help highlight any abnormality in the
breast tissue.
These tests help in diagnosing cancer. If breast
cancer is found in a person, then the doctor will advise one of these
tests to stage the breast cancer:
-
Blood test – A CBC (complete blood count) test is most useful in determining the stage of breast cancer.
-
Advanced mammogram
-
Breast MRI
-
Breast CT (computerized tomography) scan
-
Breast PET (positron emission tomography) scan
The staging process helps the doctor to determine the extent of growth
of the breast cancer and this in turn helps to determine the best-suited
breast cancer treatment for the particular case.
How is Breast Cancer treated?
There are various different methods for treatment of cancer. The
type of treatment mainly depends on several factors, such as the stage
of the cancer, its size, are of affecting along with the patient’s age,
overall heath level, etc which the doctor will consider.
These are the various types of the cancer treatments:
Surgery
Surgical removal of breast cancer is one of the most common and
effective treatment methods. In this, there are sub-types of surgical
processes that are performed, including:
-
Lumpectomy – This is a selective cancer surgery
treatment for smaller sized breast tumors. The surgeon will use a wide
local excision method to remove the cancerous tissue as well as a small
margin from the surrounding healthy tissue as well to prevent chances of
the cancer from recurring.
-
Mastectomy – This is one of the major surgeries for
cancers. It involves removing the entire mammary gland tissue, including
the lobules, fatty tissue, milk ducts, nipple, areola as well as some
portion of the skin.
-
Sentinel node biopsy – This surgical treatment of
mammary gland is helpful in determining if the cancer has spread to the
surrounding lymph nodes. The surgeon will remove a few of the
closest-situated lymph nodes near the breast to check for cancerous
cells or drainage from the tumor.
-
Axillary lymph node dissection – In case the surgeon
finds cancer cells in the sentinel lymph nodes the additional lymph
nodes near the armpit might also need to be removed surgically.
-
Contra lateral prophylactic mastectomy – This surgery
involves removing both the breast tissues completely even if the cancer
is found to be affecting one of the breasts. This is done to prevent the
risk of the cancer recurring in the affected breast and the cancer from
spreading to the other healthy breast tissue.
Radiotherapy
Radiotherapy, also known as radiation therapy, is a breast cancer
treatment method involving the use of high-energy x-rays (or protons) to
target and destroy the cancer cells in the breast tissue. Radiotherapy
can be done as an external procedure or the surgeon might use minimally
invasive surgical method to insert a small radioactive device into the
breast (brachytherapy) for closer access in giving an effective
radiation dose to the cancerous breast tissue cells.
This is
often used in combination with a surgical breast cancer treatment in
case the surgery is not able to remove the entire cancerous tissue.
Chemotherapy
Chemotherapy treatment for breast cancer involves using a combination of specially designed medicinal drugs that are aimed to destroy the cancerous cells in the breast. This treatment method is also used before treating a large sized breast tumor. The medicinal drugs are effective in reducing the size of the large cancerous tumor in the breast which can then be safely removed using surgical methods.
