The major cause of cancer is when the cells start to grow out of control and the same things when happen in the breasts of women it causes breast cancer the kind of breast cancer depends on the cells which grow abnormally. Symptoms of breast cancer are visible once the lumps are easily visible on the breast.
It contains 3 main parts
- Lobules which produce the milk.
- The duct is the tube that carries milk to the nipple.
- Connective tissue holds everything together.
Breast cancer can also be spread to other parts of the body through blood vessels and lymph that situation is called metastasizing.
Breast cancers can start from different parts of the breast.
- Most breast cancers begin in the ducts that carry milk to the nipple (ductal cancers)
- Some start in the glands that make breast milk (lobular cancers)
- There are also other types of breast cancer that are less common like phyllodes tumor and angiosarcoma
- A small number of cancers start in other tissues in the breast. These cancers are called sarcomas and lymphomas and are not really thought of as breast cancers.
How Breast cancer spreads
Lymph is a network of vessels that are found in the body throughout and that connect lymph nodes. The clear fluid inside the lymph vessel is called the lymph which contains the immunity system cells, tissue by-product cells, and waste material.
Lymph fluids are carried out of the breast by the lymph vessels. In the case of breast cancer, the cancer cells grow in the lymph nodes, and most of the lymph vessels of the breast drain into:
- Lymph nodes under the arm, collar bone, near the breast bone.
If the cancer is spread or traveled through the lymph node then there is a higher chance that it has been spread to the other parts of the body called metastasized. you will need surgery to remove one or more lymph nodes to know whether the cancer has spread.
Signs and symptoms of breast cancer may include:
- A breast lump or thickening that feels different from the surrounding tissue
- Change in the size, shape, or appearance of a breast
- Changes to the skin over the breast, such as dimpling
- A newly inverted nipple
- Peeling, scaling, crusting, or flaking of the pigmented area of skin surrounding the nipple (areola) or breast skin
- Redness or pitting of the skin over your breast, like the skin of an orange.
- Hormonal abnormality
- Genetic Makeup
- Environment factors
Types of Breast Cancer
Inflammatory breast cancer
A very rare but aggressive type of breast cancer that blocks the lymph node so that lymph vessels in the breast cannot drain properly which results in creating a tumor. It causes the breast to swell, look reddish and warm.
IBC is very aggressive and can progress very quickly so it is very important to consult the doctor if any symptoms found.
Triple-negative breast cancer
Another very rare type of breast cancer that affects only 10 to 20 percent of the people with breast. To be diagnosed as triple-negative breast cancer, a tumor must have all three of the following characteristics:
- It estrogen receptors. These are receptors at the cells that bind or attach, to the hormone estrogen. If a tumor has estrogen receptors, estrogen can stimulate the most cancers to grow.
- Lacks progesterone receptors. These receptors are cells that bind to the hormone progesterone. If a tumor has progesterone receptors, progesterone can stimulate the most cancers to grow.
- It doesn’t have extra HER2 proteins on its surface. HER2 is a protein that fuels breast most cancers growth.
If all these three criteria are fulfilled then the cancer is said to have triple-negative breast cancer. They are difficult to treat and they can grow and spread faster than other cancers.
Metastatic breast cancer
Another name of stage 4 breast cancer. It is a type of cancer that can spread from the breast to other parts of the body like bones, lungs, and liver. This is an advanced stage of breast cancer where your oncologist will make a plan to stop the growth and spread of tumor/tumors.
Ductal breast cancer In Situ

The strange cells have now no longer unfold outdoor of the ducts into the encompassing breast tissue.
Ductal breast cancer in situ could be very early most cancers this is tremendously treatable, however, if it’s left untreated or undetected, it could unfold into the encompassing breast tissue.
Invasive Ductal breast cancer
Also called infiltrative ductal breast cancer that began forming in the milk duct and spread to the other part of the breast tissue this can also be spread to other parts of the body. It is the most common type of breast cancer making up to 70-80% of diagnosis.

Stage 2 Breast Cancer Symptoms

Stage two of breast cancer symptoms

- 2B: The tumor is between 2 and five cm and has unfolded to 1–3 axillary (armpit) bodily fluid nodes, or it’s larger than five cm and hasn’t unfold to any bodily fluid nodes.
Stage 3 Breast Cancer Symptoms
- A mass or lump
- A change in the size, shape, or contour of the breast.
- A blood-stained or clear fluid from the nipple.
Stage three breast cancer
- The cancer has unfold to 4–9 axillary bodily fluid nodes or has enlarged the inner duct gland lymph nodes, and therefore the primary tumor will be any size.
- Tumors are bigger than five cm and therefore the cancer has unfold to 1–3 axillary bodily fluid nodes or any os nodes.
- 3B: A tumor has invaded the chest wall or skin and will or might not have invaded up to nine bodily fluid nodes.
- 3C: Cancer is found in ten or a lot of axillary bodily fluid nodes, bodily fluid nodes close to the bone, or internal duct gland nodes.
Stage 4 breast cancer symptoms
- Nipple discharge.
- Breast pain.
Stage four breast cancer symptoms

When it is difficult to answer about the cancer from the ultrasound and mammography then the doctor asks for a breast biopsy. In this process, the tissue is taken from the suspect area and then will send to the laboratory to test the tissue for cancer and if tested positive the lab will tell the doctor which type of cancer you are having.
Breast cancer treatments
Several types of surgery may be used to remove breast cancer, including:
- Lumpectomy: This procedure removes the tumor and a few close tissue, going the remainder of the breast intact.
- Mastectomy: During this procedure, a medico removes a complete breast. in an exceedingly double ablation, each breast is removed.
- Sentinel Node Biopsy: This surgery removes many of the lymph nodes that receive emptying from the tumor. These lymph nodes are going to be tested. If they don’t have cancer, you’ll not like further surgery to get rid of a lot of lymph nodes.
- Axillary Node Dissection: If lymph nodes removed throughout a sentinel node biopsy contain cancer cells, your doctor could take away further tumor nodes.
- Contralateral Prophylactic Ablation: Albeit breast cancer could also be a gift in just one breast, some ladies elect to own a contralateral prophylactic ablation. This surgery removes your healthy breast to scale back your risk of developing breast cancer once more.
Uses strong radiation beams to kill the cancer cells this technique uses a large machine outside of the body.

In this process, the surgeon place the seed near the suspect zone, and the see remain for a short period of time and work to destroy the cancer cells.
The two female hormones i..e estrogen and progesterone can help the growth of cancer tumors. Hormone therapy will stop producing these hormones or by blocking the hormone receptors on the cancer cells this will slow down the growth of the cancer.
