Breast cancer causes

Breast cancer remains one of the most prevalent forms of cancer affecting women worldwide. While significant progress has been made in understanding and treating this disease, there is still much to learn about its causes. Breast cancer is a multifaceted condition influenced by a range of factors, including genetics, lifestyle choices, environmental exposures, and hormonal imbalances. In this post, we will delve into the complex causes of breast cancer, shedding light on the various factors that contribute to its development.

1. Genetic Predisposition: Certain genetic mutations, such as BRCA1 and BRCA2 gene mutations, can significantly increase the risk of developing breast cancer. However, it's essential to note that only a small percentage of breast cancer cases are directly attributed to inherited genetic factors. Most cases are believed to result from a combination of genetic predisposition and environmental influences.

3. Hormonal Factors: Hormonal imbalances play a pivotal role in breast cancer development. Women with early onset of menstruation, late menopause, or a prolonged history of hormone replacement therapy (HRT) are at a higher risk. Estrogen, a hormone produced by the ovaries, has been linked to the growth of certain types of breast cancer. Additionally, the use of oral contraceptives and exposure to high levels of estrogen over an extended period may slightly increase the risk.

5. Lifestyle Choices: Unhealthy lifestyle choices can contribute to breast cancer risk. Lack of physical activity, a sedentary lifestyle, and being overweight or obese have been associated with an increased likelihood of developing breast cancer. Additionally, excessive alcohol consumption has been linked to higher breast cancer risk, making moderation essential.

7. Environmental Factors: Exposure to certain environmental factors may also play a role in breast cancer development. These include ionizing radiation, such as from medical imaging tests like mammograms, and environmental pollutants like pesticides, industrial chemicals, and air pollution. While the impact of these factors is still being researched, it is crucial to minimize exposure to potential carcinogens where possible.

9. Family History: A family history of breast cancer can elevate an individual's risk, especially if a first-degree relative (parent, sibling, or child) has been diagnosed. Although most cases of breast cancer occur in individuals without a family history, it is important for those with a history to be aware of their increased risk and consider early screening and genetic counseling.

Breast cancer symptoms

Breast cancer is one of the most common cancer in the world, women must to pay atention to the first sign of breast  cancer.

 Symptoms of breast tumors vary from person to person. Some common, early warning signs of breast cancer include:

• Skin changes, such as swelling, redness, or other visible differences in one or both breasts
• An increase in size or change in shape of the breast(s)
• Changes in the appearance of one or both nipples
• Nipple discharge other than breast milk
• General pain in/on any part of the breast
• Lumps or nodes felt on or inside of the breast

Symptoms more specific to invasive breast cancer are:

• Irritated or itchy breasts
• Change in breast color
• Increase in breast size or shape (over a short period of time)
• Changes in touch (may feel hard, tender or warm)
• Peeling or flaking of the nipple skin
• A breast lump or thickening
• Redness or pitting of the breast skin (like the skin of an orange) 

Symptoms of invasive breast cancer

Breast cancer that’s spread from where it began into the tissues around it is called invasive or infiltrating. You may notice:

• A lump in your breast or armpit. You might not be able to move it separately from your skin or move it at all.
• One breast that looks different from the other
• A rash or skin that’s thick, red, or dimpled like an orange
• Skin sores
• Swelling in your breast
• Small, hard lymph nodes that may be stuck together or stuck to your skin
• Pain in one spot

Symptoms of metastatic breast cancer

Without treatment, breast cancer can spread to other parts of your body, including other organs. This is called metastatic, advanced, or secondary breast cancer. Depending on where it is, you may have:

• Bone pain
• Headache
• Changes in brain function
• Trouble breathing
• Belly swelling
• Yellow skin or eyes (jaundice)
• Double vision
• Nausea
• Loss of appetite and weight loss
• Muscle weakness

Symptoms of triple-negative breast cancer

Breast cancer is called triple-negative if it doesn’t have receptors for the hormones estrogen and progesterone and doesn’t make a lot of a protein called HER2. This kind tends to grow and spread faster than other types, and doctors treat it differently.

Triple-negative tumors make up 10% to 15% of breast cancers. They cause the same symptoms as other common types. Get an overview on triple-negative breast cancer symptoms and treatment.

Symptoms of male breast cancer

About 1% of breast cancers happen in men. Because it’s so rare, you may not pay attention to the symptoms until the cancer has grown. Watch for:

• A lump or thick spot in your breast or armpit
• Changes in the skin of your breast or nipple, such as redness, puckering, scales, or discharge

Symptoms of Paget’s disease of the breast

This type often happens along with ductal carcinoma. It affects the skin of your nipple and areola. Symptoms may look like eczema and include:

• Nipple skin that’s crusted, scaly, and red
• Bloody or yellow discharge from the nipple
