Uterine cancer is divided into cervical cancer and endometrial cancer. Cervical cancer is a malignant tumor that occurs in the epithelium and glandular tissue of the cervix, while endometrial cancer is a group of epithelial malignant tumors that occur in the endometrium. The two types of cancer differ due to their different sites of origin. Accordingly, the examination and treatment methods adopted are also not completely the same based on the different sites of origin. However, both cervical and endometrial cancers are primarily treated with surgery, followed by corresponding radiotherapy and chemotherapy.

Late-stage symptoms of endometrial cancer

Endometrial cancer is a common malignant tumor in the female reproductive system. In advanced stages, patients often experience irregular vaginal bleeding. In addition, there may be bloody discharge from the vagina. If an infection is present or there are signs of necrosis due to the cancer, there may also be purulent discharge or other foul odors. Additionally, there are more apparent symptoms such as pain, abdominal masses, and in late stages, the cancer may invade blood vessels, causing swelling in the lower limbs, or spread to nearby organs, such as the ureters, leading to renal damage. Over time, this can also lead to cachexia, fever, and other signs of systemic failure.

Early symptoms of endometrial cancer

When endometrial cancer occurs in women, it first manifests as abnormal proliferation of the endometrium, increased endometrial surface area, and increased secretions, which can increase the pressure inside the uterine cavity, leading to lower abdominal pain in women. Most women can tolerate this pain, but it tends to worsen during vigorous activities or sexual intercourse. Vaginal discharge may become watery and increase. Additionally, some women may experience increased menstrual flow or irregular vaginal bleeding. Over time, this can lead to blood loss anemia in women, manifesting as dizziness, fatigue, and changes in appetite.

How is endometrial cancer detected?

When women experience irregular vaginal bleeding, or vaginal bleeding reoccurs after menopause, and uterine endometrial cancer is suspected, the first step is to conduct a routine gynecological examination to identify whether the bleeding originates from the uterine cavity or the cervix. Additionally, an ultrasound examination can be conducted to observe the condition inside the uterine cavity, the thickness of the endometrium, whether the thickness is uniform, and whether there are any abnormal growths, to understand whether the woman might have uterine endometrial cancer. However, these methods usually cannot provide a diagnosis and only serve to assess or suggest the possibility of endometrial cancer. For a definitive diagnosis, a hysteroscopy or diagnostic curettage can be performed, and the results of the pathological examination can confirm the diagnosis.

Is endometrial tofu dregs-like a sign of endometrial cancer?

Endometrial cancer usually manifests in five main aspects. First, irregular vaginal bleeding, which is typically light but can be moderate in some patients. If the patient is postmenopausal, the bleeding often appears as either continuous or intermittent. Second, menstrual disorders, which are a common symptom of endometrial cancer as it is a malignant tumor occurring in the endometrium and significantly affects menstruation. Third, vaginal discharge, where some patients may experience a discharge of thin, white secretions, or a very small amount of bloody discharge in the early stages of the disease. Fourth, pain; once a patient develops endometrial cancer, the tumor may cause bleeding and possibly lead to infection. Fifth, abdominal masses, which can occur if there is a combination of large uterine fibroids or in advanced stages, potentially leading to the formation of large masses in the pelvic cavity due to the spread of a uterine cavity abscess.

Is a thick endometrium the same as cancer?

Endometrial thickening is not necessarily cancerous. Causes of endometrial thickening generally include irregular hyperplasia or endometrial polyps, both of which can lead to thickening of the endometrium, but this is not necessarily indicative of cancer. Whether it is endometrial cancer is usually determined if patients with endometrial thickening do not show clear improvement after treatment with medication. Typically, a curettage procedure is performed to collect tissue for pathological examination. If the pathology report indicates endometrial cancer or precancerous lesions, then it will be reported. Therefore, endometrial thickening is not necessarily indicative of endometrial cancer, and it can occur with conditions like endometrial polyps or irregular endometrial hyperplasia. Treatment at this stage should be based on the pathological results. Thus, while endometrial thickening should be taken seriously, it is not necessarily cancerous.
