Breast Cancer (Female) (Definition)

Breast cancer results when glandular cells lining the milk ducts and lobules of the human breast begin to grow in an unregulated manner. The growth occurs initially inside the ducts but eventually breaks outside into the breast tissue and ultimately spreads both to the lymph nodes in the armpit and via the bloodstream to other parts of the body. Because of the promoting affect of estrogen almost all breast cancer occurs in women and is a rarity in men. The unregulated growth is due to both inherited and acquired genetic defects. It is the most common malignancy in women but it often curable if found early and treated effectively with surgery, hormonal therapy, chemotherapy and targeted therapy, or a combination thereof. Early detection before the malignancy becomes large enough to be felt depends on mammography/sonography and MRI imaging of the breast on an annual basis. ...Read more

What to do if I have a small lump under my armpit.. and it feels as though I have lumps in my breasts, too. could this be breast cancer?

What to do if I have a small lump under my armpit.. and it feels as though I have lumps in my breasts, too. could this be breast cancer?

Always possible: small lumps in armpit are usually of no concern unless they are enlarging and increasing in number. Lumps in the breast are usually normal since by definition breast tissue is lumpy. A solitary firm lump always requires investigation. Either way a mammo and sono should be performed and any further treatment would proceed from there. ...Read more

Neck, shoulder/armpit, arm pain, and a couple lumps in breast felt by dr.  All on l side. I'm 23 years old. Breast cancer?

Not always/depends,,: It doesn't always mean cancer. This can be fibrocystic disease with cysts that come and go with your cycle due to the hormones produced. It can also be benign lumps like fibroadenomas and the neck pain, etc. Can be unrelated. More tests like biopsy and scans may be needed, especially if you've got a family history of breast cancer so see your doctor to talk about what to do. Good luck. ...Read more

Does lump on the armpit always means breast cancer? I'm having it on my right armpit :(

No: Armpit lumps are rather common and can be due to a number of things including insect bites, rashes, swollen glands, and breast cancer. In your age group, breast cancer would be extremely uncommon. If this lump grows in size or does not start getting smaller over the next 2-4 weeks, you should definitely see a medical doctor for a full evaluation. ...Read more

What type of breast cancer that cause the breast to swell and cause under the armpit to have a painful lump? And does that mean the cancer has spread

What type of breast cancer that cause the breast to swell and cause under the armpit to have a painful lump? And does that mean the cancer has spread

Possibly IBC: Inflammatory breast cancer occurs suddenly with breast pain, redness, or swelling. It is very fast-growing and spreads quickly. It looks like an infection, so doctors often try antibiotics first, delaying diagnosis. However, infection is also a possibility. See a doctor immediately for these symptoms. If it is cancer, your symptoms don't mean it has spread. But you need a biopsy of any lump! ...Read more

Need to examine: If is not feasible to know what you are feeling. You may be feeling a rib rather than a mass in the breast. It would be prudent to see your doctor for an evaluation. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more
