Invasive and non-invasive differ in pathological definition, biological characteristics, treatment and prognosis.
1. Definition: Invasive carcinoma refers to the cancer cells breaking through the basement membrane and infiltrating to deeper levels in pathological examination. Non-invasive carcinoma, also known as carcinoma in situ and intraepithelial carcinoma, refers to cancer cells confined to the epithelium without breaking through the basement membrane.
2. Biological characteristics: invasive carcinoma is more malignant and easier to spread and metastasize. Non-invasive cancer is less malignant and less likely to spread and metastasize.
3. Treatment: invasive carcinoma usually requires radical surgery, radiotherapy, chemotherapy and other comprehensive treatments. Non-invasive cancer usually requires tumor resection, and whether radiotherapy is needed depends on the type of tumor, malignant degree and other selective treatments.
4. Prognosis: Invasive carcinoma generally has a worse prognosis than non-invasive carcinoma. Non-invasive carcinoma can be regarded as pre-cancerous lesions, and early detection and treatment of non-invasive carcinoma can prevent it from developing into invasive carcinoma.
Patients are advised to consult a specialist and follow the doctor’s instructions for further examination and treatment.
