What is molar tissue pregnancy?

The tissue comes from cells that normally help form the placenta, but it grows in an abnormal pattern. In a complete mole, fetal development is absent. In a partial mole, some fetal tissue may be present but the pregnancy cannot develop normally. The tissue produces hCG, so hormone levels may be higher or behave differently than expected.

Possible symptoms include vaginal bleeding, pelvic discomfort, unusually severe nausea and symptoms related to pregnancy hormones. Some people have no clear symptoms and are diagnosed during ultrasound. The diagnosis may be refined by examining tissue after it is removed.

The gynaecology team usually removes the molar tissue and arranges follow-up blood tests. hCG should decline in a predictable pattern; a plateau or rise needs prompt review because active tissue may remain. Keep a record of appointments and tell the team about medicines, new symptoms and any possibility of pregnancy.

Avoid conception until your specialist confirms that monitoring is complete. This protects your health plan and prevents a new pregnancy from making hCG results hard to interpret. You can ask for grief counselling or other support after the loss of a wanted pregnancy.

Seek urgent care for heavy bleeding, faintness, severe abdominal pain, fever, persistent vomiting, chest pain, breathing difficulty, or a severe headache with visual changes. Tell the clinician that molar tissue has been diagnosed or treated. Report hCG results that stop falling or begin to rise to the specialist team without waiting for a routine appointment.

Ask whether the tissue is complete or partial, how it will be removed, what the pathology examination can show, and which hCG schedule applies to you. Confirm contraception advice, the symptoms that need urgent review, when future pregnancy can be considered, and when additional treatment such as chemotherapy might be discussed.
