背景技术Background technique
常见的妇科肿瘤有外阴肿瘤、阴道肿瘤、子宫肿瘤、卵巢肿瘤和输卵管肿瘤。以子宫及卵巢肿瘤多见，外阴及输卵管肿瘤少见。一旦患有妇科肿瘤，通常会有如下表现：Common gynecological tumors include vulvar tumors, vaginal tumors, uterine tumors, ovarian tumors, and fallopian tube tumors. Tumors of the uterus and ovary are more common, while tumors of the vulva and fallopian tubes are rare. Once suffering from gynecological tumors, there are usually the following manifestations:
阴道出血要与正常月经区别。阴道出血常表现为月经量增多，月经期延长，不规则的出血，或排出血水，血的颜色发生改变。白带的改变。正常白带应该是白色糊状或蛋清样，清亮、无味、量少。当白带量增多，颜色发生改变，如浓样、血样及水样、有异味，应及时到医院进行检查。下腹部出现肿块。通过盆腔检查，可以触及增大的子宫及肿块。肿块过大可以在腹部触摸到。可能有囊性感，也可有实性感，软硬程度不同。下腹痛多为妇科疾病引起。肿瘤可以引起下腹痛，如肿瘤蒂扭转、破裂、发生炎症、出血，出现腹水等，均可出现不同程度的下腹痛、增大的肿瘤可以压迫肛门，有坠胀感。大.小便改变：肿瘤压迫或侵袭可引起闭尿、尿频、血便甚至尿瘘或粪瘘。这些都是妇科肿瘤常见的症状，无论出现哪些症状，或轻、或重，都要及时到医院检查，通过盆腔检查及各种不同的辅助检查基本可以判断。Vaginal bleeding should be distinguished from normal menstruation. Vaginal bleeding often manifests as increased menstrual flow, prolonged menstrual periods, irregular bleeding, or discharge of blood, and changes in blood color. Leucorrhea changes. Normal leucorrhea should be white paste or egg white-like, clear, tasteless, and less in quantity. When the amount of leucorrhea increases and the color changes, such as thick samples, blood samples, water samples, and peculiar smell, you should go to the hospital for examination in time. Lumps in the lower abdomen. An enlarged uterus and mass can be palpated through a pelvic examination. The mass is too large to be palpable on the abdomen. It may be cystic or solid, with different degrees of softness and hardness. Lower abdominal pain is mostly caused by gynecological diseases. Tumors can cause lower abdominal pain, such as tumor pedicle torsion, rupture, inflammation, bleeding, ascites, etc., can cause lower abdominal pain to varying degrees, and enlarged tumors can oppress the anus, causing a sense of swelling. Changes in urine and urine: tumor oppression or invasion can cause anuresis, frequent urination, bloody stools, or even urinary or fecal fistula. These are common symptoms of gynecological tumors. No matter what symptoms appear, whether they are mild or severe, you should go to the hospital for examination in time. You can basically judge them through pelvic examination and various auxiliary examinations.
现有治疗妇科肿瘤的方案有宫·腹腔镜疗法、消融技术和卵巢癌治疗验方偏方；Existing treatment options for gynecological tumors include hystero-laparoscopic therapy, ablation techniques, and proven prescriptions for ovarian cancer;

妇科疾病不同于其他疾病，在不同的年龄阶段可患不同类型的病，如青春期、育龄期、绝经期，各自有不同的疾病特征。有的疾病与月经及妊娠有关，有时是生理和病理相类似的表现，但有区别。有些全身性恶性疾病可以向生殖器官转移，妇科的恶性肿瘤也可以向一些器官及全身转移。Gynecological diseases are different from other diseases, and different types of diseases can be suffered at different ages, such as adolescence, childbearing age, and menopause, and each has different disease characteristics. Some diseases are related to menstruation and pregnancy, and sometimes they have similar physiological and pathological manifestations, but there are differences. Some systemic malignant diseases can be transferred to reproductive organs, and gynecological malignant tumors can also be transferred to some organs and the whole body.
妇科肿瘤分为良性和恶性，良性和恶性肿瘤都有囊性和实性之分。根据不同的部位可以分为：外阴肿瘤、阴道肿瘤、子宫肿瘤、卵巢肿瘤和输卵管肿瘤。以子宫及卵巢肿瘤多见，外阴及输卵管肿瘤少见。Gynecological tumors are divided into benign and malignant, and both benign and malignant tumors are divided into cystic and solid. According to different parts, it can be divided into: vulvar tumor, vaginal tumor, uterine tumor, ovarian tumor and fallopian tube tumor. Tumors of the uterus and ovary are more common, while tumors of the vulva and fallopian tubes are rare.
子宫肌瘤是最常见的良性肿瘤。多发生30～50岁，以40～50岁为多见，20岁以下少见。据统计约有1/3的妇女患有不同程度的子宫肌瘤，常因子宫肌瘤小，无症状，不做妇科检查而未做诊断。一般情况下，子宫肌瘤小，对月经无明显影响时，可以暂时不做治疗。绝经后由于激素水平的改变，子宫和卵巢要萎缩，肌瘤也会相应缩小，但需做定期检查。如果子宫肌瘤逐渐长大，有些肌瘤可以影响月经，出现月经量明显增多，月经期延长，易引起贫血。或者肌瘤发生变性，就需要及时治疗。子宫肌瘤恶性变的比较少。Uterine fibroids are the most common benign tumors. Most of them occur in 30-50 years old, more common in 40-50 years old, and rare in people under 20 years old. According to statistics, about 1/3 of women suffer from different degrees of uterine fibroids, often because the uterine fibroids are small and asymptomatic, and they are not diagnosed without gynecological examination. Under normal circumstances, when uterine fibroids are small and have no obvious impact on menstruation, treatment can be temporarily omitted. After menopause, due to changes in hormone levels, the uterus and ovaries will shrink, and the fibroids will shrink accordingly, but regular inspections are required. If the uterine fibroids grow gradually, some fibroids can affect menstruation, and the menstrual volume will increase significantly, and the menstrual period will be prolonged, which will easily cause anemia. Or fibroids degeneration, you need to be treated in time. Uterine fibroids are less malignant.
卵巢肿瘤分为良性肿瘤和恶性肿瘤，卵巢良性肿瘤也有可能转变为恶性。卵巢肿瘤种类繁多、复杂，而且身体内其他原发性恶性肿瘤，可以向卵巢转移，如乳腺、肠、胃肿瘤等。发现卵巢肿瘤，不管良胜、恶性都应及时到医院检查。良性肿瘤可以手术治疗，恶性肿瘤也可以手术治疗和化学药物治疗及放射治疗。Ovarian tumors are divided into benign tumors and malignant tumors, and benign tumors of the ovary may also turn into malignant tumors. Ovarian tumors are various and complex, and other primary malignant tumors in the body can metastasize to the ovary, such as breast, intestinal, and gastric tumors. Ovarian tumors are found, regardless of whether they are benign or malignant, they should go to the hospital for examination in time. Benign tumors can be treated with surgery, and malignant tumors can also be treated with surgery, chemotherapy and radiation therapy.
