How is hemangioma treated?
Currently, common methods used for the treatment of hemangiomas include medication, laser therapy, and surgical treatment. There is no single method that can treat all types of hemangiomas. The choice of treatment should be based on factors such as the type, location, depth of the tumor, and the patient's age. Common methods include surgical removal, radiation therapy, cryosurgery, sclerotherapy injections, and laser treatment. The principles of treatment are: first, to prevent or treat serious life-threatening and functional complications; second, to prevent deformities or facial defects after the regression of the hemangioma; third, to prevent ulcers and infections, and for patients who have ulcers, to promote ulcer healing, reduce scarring, and alleviate pain; fourth, to reduce the psychological stress on the child and their family; fifth, to avoid overtreatment of lesions that can regress on their own and have a good prognosis.
Can pancreatic cancer patients eat eggs?
The dietary principles for pancreatic cancer are: First, eat nutritionally rich foods; second, pay attention to reasonable combinations; third, adjust the dietary structure; and fourth, appropriately include some fungi. Patients with pancreatic cancer should first consider nutrition in their diet, and can eat more high-protein, high-carbohydrate foods, such as fish, liver, eggs, milk, vegetable soup, etc., to supplement the nutrients and energy needed by the body. Based on their actual physical condition, they should adjust their diet structure and ensure nutritional balance. Therefore, it is acceptable for pancreatic cancer patients to eat eggs.
How is pancreatic cancer diagnosed?
Ultrasound, CT, MRI, ERCP (Endoscopic Retrograde Cholangiopancreatography), PTCD (Percutaneous Transhepatic Cholangio Drainage), angiography, laparoscopy, tumor markers measurement, cancer gene analysis, etc., are significantly helpful in confirming the diagnosis of pancreatic cancer and determining whether it is resectable surgically. Generally, ultrasound, CA199, and CEA can be used as screening tests. Once pancreatic cancer is suspected, a CT scan is necessary. If the patient has jaundice, especially severe, and a CT scan cannot confirm the diagnosis, ERCP and PTCD can be considered. If internal drainage is successful, surgery can be delayed for one to two weeks for patients with severe jaundice. The diagnostic value of MRI for pancreatic cancer is not superior to CT. If pancreatic cancer has been confirmed but it is uncertain whether it can be surgically removed, choosing angiography and laparoscopy is also clinically meaningful.
Can hemangiomas be left untreated?
Hemangiomas on the head and face, and those around the eyes, tend to invade the eyeballs or cause complications such as glaucoma. Hemangiomas in the parotid gland area can compress or damage the facial nerve, leading to facial paralysis. Nasal hemangiomas may block the nasal passages, causing deformities of the nostrils. Lip hemangiomas, due to friction from sucking or eating, are prone to rupture causing deformities of the lip; ear hemangiomas, because of poor blood circulation, are prone to infection after rupture. Hemangiomas on the limbs and body, due to the rapid growth of some, can invade muscle tissue, bones, or joints, causing local pain and, in severe cases, joint deformities and other functional symptoms. Therefore, it is necessary to treat hemangiomas.
Will hemangiomas resolve on their own?
Pediatric hemangiomas are relatively common congenital disorders in pediatric surgery, frequently found on the face, body surface, and limbs. They appear as red or purplish-red protruding lumps with clear boundaries. These lumps do not blanch when pressed, grow in size with the child's growth and development. Clinically, pediatric hemangiomas are categorized into capillary hemangiomas, cavernous hemangiomas, and racemose hemangiomas. Capillary hemangiomas in children often disappear on their own within one to two years, while cavernous and racemose hemangiomas usually require surgical treatment. Thus, it is said that pediatric capillary hemangiomas can regress spontaneously.
What are the symptoms of pancreatic cancer?
The clinical manifestations of pancreatic cancer mainly depend on the location of the cancer, the stage of the disease, whether there is metastasis, and the involvement of adjacent organs. The clinical characteristics include a short disease course, rapid progression, and swift deterioration. The most common symptom is upper abdominal distension and discomfort, pain, though not all patients experience tenderness; if tenderness is present, it aligns with the area of pain felt. Pain is a primary symptom of pancreatic cancer, present whether the cancer is located in the head or the body/tail of the pancreas. Jaundice is a main symptom of cancer in the head of the pancreas, and patients often exhibit more severe gastrointestinal symptoms, most commonly loss of appetite, followed by nausea and vomiting. There might also be diarrhea or constipation, even melena. Diarrhea is often steatorrhea. In the early stages of pancreatic cancer, common symptoms include weight loss and fatigue.
Can hemangiomas go untreated?
The severity of harm varies with different types of hemangiomas, such as in adults with mixed-type hemangiomas. These can continually develop as the patient ages. If the affected areas expand further, they may extend to tissues and organs like the eyes, nose, lips, or ears. These organs might then become covered by the expanding vascular tissue, potentially causing impairments in functions such as breathing, eating, vision, and hearing. If hemangiomas appear on the limbs, they can also lead to dysfunction, affecting mobility. Therefore, it is advisable to seek treatment for hemangiomas as early as possible.
How are hemangiomas formed?
The etiology of hemangioma is unknown. Studies have shown that the use of progesterone during pregnancy, undergoing chorionic villus sampling, hypertensive disorders during pregnancy, and low birth weight at the time of birth may be related to the formation of hemangiomas. It is believed that hemangiomas are a result of minor misconfigurations in the control gene segments during the embryonic development process, particularly during the early stages of vascular tissue differentiation. This leads to abnormal tissue differentiation at specific sites, eventually developing into hemangiomas. During the early months of embryonic development, from eight to twelve months, mechanical damage to embryonic tissue and local bleeding can cause some hematopoietic stem cells to be distributed among other embryonic cells, some of which differentiate into vessel-like tissues and ultimately form hemangiomas.
Is a hemangioma a tumor?
Hemangiomas are formed by the proliferation of vascular endothelial cells during embryonic development and are commonly seen in congenital benign tumors or vascular malformations of the skin and soft tissues, mostly observed at birth or shortly after birth. The residual embryonic vascular endothelial cells, active endothelial-like embryonic buds invade adjacent tissues, forming endothelial-like cords, which after canalization connect with existing blood vessels to form hemangiomas. The blood vessels within the tumor form a separate system, not connected to surrounding blood vessels. Hemangiomas can occur throughout the body; those occurring in the oral and maxillofacial regions account for 60% of all hemangiomas, followed by 25% in the trunk and 15% in the limbs. Therefore, some hemangiomas are congenital benign tumors, while others are caused by vascular malformations.
Pancreatic cancer is a type of cancer that arises from the pancreas.
The causes of pancreatic cancer are not yet entirely clear, but its occurrence is associated with smoking, drinking alcohol, high-fat and high-protein diets, excessive consumption of coffee, environmental pollution, and genetic factors. Recent surveys have found that the incidence of pancreatic cancer is significantly higher among diabetics than in the general population. There is also evidence suggesting a certain relationship between chronic pancreatitis and the development of pancreatic cancer, with a notably increased risk of pancreatic cancer among patients with chronic pancreatitis. Additionally, many other factors such as occupation, environment, and geography are somewhat related to the occurrence of this disease. Pancreatic cancer is not a cancer that comes from anger or emotional causes.
