Patients with endometrial cancer generally have factors such as hypertension, diabetes, and obesity that induce the condition. They are more prone to developing endometrial cancer. Furthermore, endometrial cancer is divided into hormone-dependent and non-hormone-dependent types. Hormone-dependent endometrial cancer occurs when there is an excess of estrogen produced in the body without sufficient counteraction by progesterone, leading to excessive growth and proliferation of the endometrial lining. When this growth becomes uncontrolled, it can lead to cancer. Non-hormone-dependent endometrial cancer is not caused by hormonal factors and its development is more complex. Additionally, the pathology type of non-hormone-dependent endometrial cancer is also quite unique.

Endometrial cancer leukorrhea symptoms

The main manifestation of endometrial discharge is an increase in the amount of discharge, which can be watery or bloody. Sometimes, it can also appear as pus-blood-like discharge. Another main symptom of endometrial cancer is irregular vaginal bleeding. During an ultrasound, uneven echoes can be seen within the uterine cavity. The patient may also experience pain in the lower abdomen and increased menstrual flow. Therefore, if there are abnormalities in menstruation or unusual vaginal discharge, it is necessary to promptly go to the hospital for an ultrasound and gynecological examinations, and receive treatment based on the results of these tests.

What to do about endometrial cancer pain?

Endometrial cancer, when cancerous tissues invade local nerves, can cause patients to experience pain. This type of pain is recommended to be alleviated by oral painkillers. Pain caused by cancer is an important factor affecting the quality of life of patients in the middle and late stages of the disease; therefore, in clinical practice, analgesic medications can be administered to relieve symptoms in patients with cancer pain. (Please take medications under the guidance of a doctor.)

What are the symptoms of endometrial cancer?

Patients with endometrial cancer mainly experience symptoms in three areas: First, obvious symptoms caused by local tumors in the uterus, such as irregular vaginal bleeding, changes in the menstrual cycle, a sense of fullness and dull pain in the lower abdomen and pelvic area, along with significant discomfort and pain. Second, clinical symptoms caused by metastatic lesions. Endometrial cancer can spread through three pathways, which after dissemination can cause a variety of symptoms, such as abdominal pain, bloating, constipation, headache, vomiting, movement disorders, chest tightness, coughing, wheezing, and difficulty breathing. Some patients may also experience bone pain. Third, systemic symptoms, which are typically seen in advanced stages of endometrial cancer and commonly include cachexia, fever, and others.

Is endometrial hyperplasia cancer?

Endometrial hyperplasia is not the same as endometrial cancer; it can be treated promptly. Endometrial cancer develops from ongoing endometrial hyperplasia, which can progress into atypical hyperplasia, a precancerous condition of the endometrium. Further development can lead to endometrial cancer. Therefore, it is crucial to treat endometrial hyperplasia actively to prevent its progression to endometrial cancer. Endometrial hyperplasia results from a lack of progesterone influence, causing the endometrium to remain in a proliferative state rather than transitioning to the secretory phase. With the influence of progesterone, the endometrium would not undergo hyperplasia; therefore, treating endometrial hyperplasia with progesterone is advisable.

Is endometrial hyperplasia the same as cancer?

Endometrial hyperplasia is not cancer; it is caused by a prolonged absence of ovulation, which means there is no secretion of progesterone. This prevents the proliferative phase endometrium from transforming into the secretory phase, leading to hyperplasia. If the hyperplasia persists over an extended period, it may lead to precancerous changes in the endometrium, and in severe cases, it can cause endometrial cancer. Therefore, it is essential to treat endometrial hyperplasia with progesterone, which can transform the endometrium and allow it to shed completely, altering its condition and restoring it to normal. As long as there is ovulation, there is the production of progesterone, so promoting ovulation is crucial.
