Noticing a lump above your caesarean section scar can be worrying. Understanding what might be causing the lump will help you make informed decisions about your health. Read on to learn more about haematoma, scar tissue, incisional hernia, and endometriosis, and find out what steps to take next.
Causes of a lump above caesarean section scar:
- Haematoma: A haematoma is a common reason for a lump near a caesarean section scar. It occurs when blood collects in the tissues surrounding the wound. Initially, the lump may appear along with discolouration similar to a bruise. Over time, the skin may release old blood as the haematoma resolves. If you notice any signs of the wound reopening or not healing, it's important to speak with your doctor promptly.
- Scar tissue: Scar tissue forms when the body's tissues are damaged during a caesarean section. As part of the healing process, the body produces collagen, a protein that aids in healing and strengthening the wound. Over a period of three months or longer, collagen builds up at the wound site, resulting in a raised, lumpy, and red scar. Eventually, some collagen breaks down, blood supply decreases, and the scar gradually becomes smoother, softer, and paler. Although scars are permanent, they may fade over time, typically within two years1.
- Incisional hernia: Having undergone a caesarean section can weaken the muscles in your abdominal wall, potentially causing tissue to bulge through a weakened area in your pelvic region. If you have an incisional hernia, you may experience tenderness and pain when moving, coughing, or lifting. It's important to seek medical attention if you suspect an incisional hernia2.
- Endometriosis: Although rare, endometriosis can develop when the lining of the uterus (endometrium) sheds and attaches to scars and other abdominal organs instead of being released normally during menstruation. As the endometrium thickens and grows each month, lumps can form. Some women may notice tenderness, especially during menstruation. If you suspect endometriosis, it is essential to consult your doctor for a proper evaluation3.
Next Steps
If you discover a lump above your caesarean section scar, it is recommended to schedule an appointment with your general practitioner (GP) as soon as possible. Your GP will assess the lump, determine its cause, and provide guidance on any necessary treatment. Seeking prompt medical attention will ensure you receive the appropriate care and peace of mind.
Coming across a lump above your caesarean section scar can be concerning, but understanding the potential causes can help you take appropriate action. Whether it's a haematoma, scar tissue, incisional hernia, or endometriosis, consulting your doctor is crucial for accurate diagnosis and treatment. Remember to prioritise your health and seek medical advice if you notice any changes or abnormalities near your scar.
