What can I do? Could it be cancerous?

It is important to consult a doctor to have the lump evaluated, especially if it is changing in size and color. While cancer is not typically the most common cause of lumps, it is always best to have a medical professional examine it to provide an accurate diagnosis and appropriate treatment. If you do not have a family doctor, you can use online resources to find nearby medical clinics with availability for appointments. Always prioritize your health and seek medical guidance for any concerning symptoms.
