Why do I have breast pain and disturbed metabolism?

Yes, it's possible for breast cancer to show up quite quickly, in as little as 6 months. Being alert to any changes and consulting your doctor if something seems unusual is critical for early detection and treatment.

If you are experiencing pain in your left breast and feel something moving inside, it is important to consult a doctor. These symptoms may be due to various reasons, and it is best to visit a breast specialist or a general surgeon for proper diagnosis and treatment. They can guide you with the appropriate care and tests needed.

Nipple pain can result from different causes including fluctuating hormone levels, infection, or skin diseases. Pay close attention to the following if you notice that your breasts are swollen, changing their color, or have a discharge. All these symptoms may need some more checking. If you feel that it is just a minor one and it does not affect you that much, you could simply wear a well-fitted bra and have a warm compress on. Moreover, staying clean by regularly taking baths and changing your undergarments is crucial. Regardless, if the pain continues to ache or become more intense, it is strongly advised to see a healthcare professional. 

The painful breast mass you're experiencing could be due to various conditions, such as fibroadenomas or breast cysts, but it’s important to take note of it. However, if the lump has been present for two years and is now growing and becoming more painful, it's crucial to rule out more serious conditions like breast cancer. Since I can’t examine you in person, I strongly recommend seeking medical attention immediately, especially given these changes. The earlier treatment begins, the better the potential outcome.
