What should I do if I find a lump while performing a monthly breast self-exam?

Finding a lump during a breast self-exam doesn't automatically mean it's cancerous, but it's crucial to seek professional medical attention immediately. Schedule an appointment with your doctor or gynecologist as soon as possible to have the lump evaluated. They will perform a thorough examination and may order further tests, such as a mammogram or ultrasound, to determine the nature of the lump and provide an accurate diagnosis and appropriate treatment plan. Do not delay seeking medical advice.

Finding a lump during a breast self-exam doesn't automatically mean it's cancer, but it's crucial to see a doctor as soon as possible. Don't panic, but do schedule an appointment promptly. 
Here's what you should do:

• Note the details: Try to remember (or write down) the lump's location, size, shape, consistency (hard, soft, lumpy), and whether it's tender to the touch. Any changes to your breast (skin texture, nipple discharge, etc.) should also be noted.
• Schedule an appointment: Contact your doctor or gynecologist for an appointment. Explain what you've found. They may want to see you sooner rather than later.
• Avoid self-diagnosing: Do not try to diagnose yourself based on online information. A professional medical evaluation is essential.
• Don't delay: Early detection is key for successful treatment of any breast issue. Prompt medical attention will provide peace of mind and appropriate medical management.

Your doctor will likely conduct a clinical breast exam and may order further tests like a mammogram or ultrasound to determine the nature of the lump. Remember, many breast lumps are benign, but it's vital to get them checked by a medical professional.
