What are the symptoms of lung cancer?
The most common symptoms of lung cancer include coughing, particularly irritating coughs, and symptoms of coughing up blood. The blood in the sputum may appear as spots, streaks, or intermittent small amounts. Other symptoms include difficulty breathing and chest pain, as well as potential tightness in the chest, shortness of breath, and fever. Secondly, if lung cancer grows within the thoracic cavity and spreads, invading nearby tissues and organs, it can produce secondary symptoms. For example, paralysis of the phrenic nerve on the same side may lead to difficulty breathing and belching. Compression of the recurrent laryngeal nerve may cause hoarseness; compression of the superior vena cava can lead to distended veins in the face, neck, and upper limbs; subcutaneous edema; and if the pleura is invaded, it can cause pleural effusion, among other symptoms. If lung cancer metastasizes through the bloodstream, it may spread to the brain and potentially lead to symptoms such as headaches, nausea, and vomiting. Metastasis to different regions of the brain might cause various symptoms, including seizures, mental confusion, and vision impairment. In a minority of cases, lung cancer may produce endocrine substances, possibly leading to symptoms like severe muscle weakness, bone and joint pain, and other such symptoms.

Late-stage symptoms of cervical cancer
The symptoms of advanced cervical cancer start with vaginal bleeding. In the later stages, the bleeding becomes irregular and possibly heavy. The second symptom is vaginal discharge. In advanced stages, due to cancerous tissue necrosis accompanied by infection, there can be a large amount of foul-smelling, watery, or purulent discharge. The third point about advanced symptoms depends on the extent of the cancerous area involved. Secondary symptoms may appear depending on the adjacent tissues, organs, and nerves affected, including frequent urination, urgency, constipation, swelling and pain in the lower limbs. When the tumor compresses or involves the ureter, it can cause ureteral obstruction, hydronephrosis, and uremia. In the advanced stages, patients may experience symptoms of systemic failure like anemia and cachexia.

Cervical Cancer Staging Criteria
For the staging of cervical cancer, the staging criteria of the International Federation of Gynecology and Obstetrics (FIGO) are now adopted. Staging should be done before treatment, and since the FIGO staging of the cervix mainly relies on the examination of the pelvis, it is emphasized that the pelvic examination must be performed by two senior gynecologic oncologists. The staging primarily involves assessing the size of the cervical lesion, particularly the measurement of endophytic tumors, parametrial tissue infiltration, and the status of pelvic lymph nodes. However, these stages mainly rely on radiological examinations, primarily magnetic resonance imaging (MRI), to provide objective data for staging.

Will people with lung cancer experience weight loss?
This question should be answered specifically. Some people may initially experience symptoms such as weight loss and fatigue when they start to develop lung cancer. Some people with better physical constitution may not lose weight so easily. However, if a malignant tumor persists in the body for a long time, it will consume the body's nutrients and lead to a state of cachexia, characterized by systemic toxicity symptoms including weight loss, fatigue, fever, and other similar symptoms.

How is breast cancer treated?
For the comprehensive treatment of malignant (breast cancer), it needs to be specifically addressed based on case analysis, considering the patient's physical condition, economic factors, and other circumstances. There isn't a one-size-fits-all treatment plan suitable for everyone, as each case requires specific analysis. The treatment options for breast cancer include, firstly, surgery, which can be either a mastectomy or breast-conserving surgery, depending on lymph node metastasis and pathological staging. The second option includes radiation therapy, the third is endocrine therapy, the fourth is chemotherapy, the fifth is targeted therapy, and the sixth and subsequent options may include immunotherapy.

Symptoms of rectal cancer recurrence
The symptoms of rectal cancer recurrence can include changes in bowel habits and stool characteristics, possibly presenting as rectal bleeding, increased frequency of bowel movements, a sensation of heaviness in the anus, and changes in stool shape, such as narrowing. The second symptom may be abdominal pain, particularly persistent and subtle pain. The third symptom involves palpable abdominal lumps or masses, especially with right-sided colon cancer. The fourth symptom is intestinal obstruction, which can occur if the bowel is blocked due to the recurrence of rectal cancer, leading to symptoms of intestinal obstruction. The fifth symptom, if the recurrent rectal cancer has metastasized, may lead to symptoms at the respective metastatic sites.

Causes of cervical cancer
The causes of cervical cancer are particularly associated with human papillomavirus (HPV) infection. The primary causes that can lead to precancerous lesions and cervical cancer itself, in a minority of cases, do not detect HPV DNA, especially in older patients. Epidemiological studies show that early childbirth and multiple childbirths are highly related to the incidence of cervical cancer; as the number of childbirths increases, the risk of cervical cancer also increases. Smoking can suppress the body's immune function and may promote cancer development. Men who have had penile cancer, prostate cancer, or previous cervical cancer are at high risk; therefore, women who have contact with high-risk men are also more susceptible to cervical cancer.

What are the symptoms of ovarian cancer?
In the early stages, ovarian cancer often doesn't show many symptoms and can be detected during gynecological examinations. However, as it progresses, symptoms such as abdominal bloating, lumps in the abdomen, and ascites may occur. The severity of these symptoms depends on the size and location of the tumor, the extent to which it has invaded nearby organs, the histological type of the tumor, and whether the malignant tumor, ovarian cancer, has metastasized to other areas or is accompanied by other complications.

Late-stage symptoms of cervical cancer
What are some symptoms of late-stage cervical cancer? First, there may be vaginal bleeding, characterized by irregular vaginal bleeding. The amount of bleeding varies depending on the size of the lesion and the invasion of interstitial blood vessels. In the late stages, as major blood vessels may be eroded, significant bleeding can occur. The second symptom is vaginal discharge, which is often increased and may be white or blood-stained. Third, late-stage symptoms may include secondary symptoms such as involvement of adjacent tissues and organs and affected nerves, leading to frequent urination, urgency, constipation, swelling and pain in the lower limbs. Cancer pressing on the ureters can cause obstruction of the ureters, hydronephrosis, and uremia. Late stages may also present with symptoms of systemic failure such as anemia and cachexia.

Symptoms of brain metastasis from lung cancer
Brain metastasis of lung cancer is caused by hematogenous spread of lung cancer to the brain. Brain metastasis typically presents with symptoms such as headaches, nausea, and vomiting, including projectile vomiting. The headaches may be severe, and there may be abnormalities in sensory perception and motor function, possibly accompanied by seizures, mental confusion, olfactory disturbances, visual impairments, and other symptoms. The specific symptoms can vary depending on the location of the metastasis in the brain. However, most patients experience headaches, nausea, and vomiting. Individual differences are significant, and it's important to analyze the specific issues and the specific areas of the brain affected.
