If you notice that one of your breasts has changed size or shape suddenly, pay attention and consult your doctor.
The appearance of lumps or hardened masses can be a warning sign. Don't hesitate to get checked if you notice it.
Although breast pain is common, if it persists or is not related to your menstrual cycle, it is important to have it checked.
If you notice any type of discharge (such as clear fluid, blood, or pus), do not ignore it.
The skin in the area may show redness, dimpling, or a texture similar to orange peel.
If the nipple sinks inward or changes its usual position, it is worth consulting.
Remember that these symptoms do not always indicate the presence of cancer, but if you detect any, it is best to see a specialist for a more detailed evaluation. Early detection makes the difference.
