you believe that dogs can smell skin cancer. It's amazing. Recently, it was reported that a dog even smelled that the owner had skin cancer and saved the owner's life. It's amazing. Although such cases are rare, we should pay attention to skin cancer in our daily life. What are the early symptoms of skin cancer?
A 42 year old woman in New York adopted Victoria, a one eyed stray dog, in 2016. In the spring of 2017, Victoria suddenly looked at the red spot on the right side of Gao's nose and kept sniffing. Gao felt something was wrong. Only after seeing a doctor did she find skin cancer. Due to the timely discovery, Gao's wound is recovering. Now, the wound is recovering The story of people and dogs saving each other has become a good story.
According to American media "Yahoo lifestyle", Victoria kept hearing the red dot on the right side of Gao Hill's nose at that time. At first, Gao Hill didn't think it was acne. After that, the red dot once disappeared, but it reappeared a few weeks later. Victoria once again made the above move, which also made Gao Hill decide to see a doctor. After examination, she was found to have basal cell carcinoma. Doctors then operated on her to remove the infected skin and remove a piece of skin from her nose to cover the wound.
Gohir said her nostrils now look like they're hooked by a fishhook, but it's up to the wound to be healed before plastic surgery can be done. She revealed that when she was young, she used to do artificial sun exposure, which may be the cause of her skin cancer, and then she would be more careful about the sun exposure.
What are the early symptoms of skin cancer?
Squamous cell carcinoma and basal cell carcinoma are common in the early stage of skin cancer. Squamous bracteoles cancer has a high degree of malignancy. It is often found in the skin, mucous membrane and the junction of skin and mucous membrane of the head and neck, limbs, trunk and other parts. Ulcers can be formed in the early stage and grow infiltratively. When it is immersed in deep tissue, it is often accompanied by suppurative infection and lymph node metastasis. It is easy to develop on the basis of pigmented xeroderma and senile keratosis. Basal cell carcinoma (BCC) is common in the elderly, mainly in the forehead, orbit, eyelid, nasal side, ear and other places. The malignant degree of BCC is relatively low, the growth is very slow, the course of disease is more than 10-20 years, it is very common. At the beginning, BCC is usually a small thickening piece, and gradually appears to be swelling and infiltrating around, with little metastasis. Skin cancer accounts for about 1.5% of all malignant tumors in China. The incidence of skin cancer in the south is higher than that in the north.
The incidence of skin cancer is very low in China, but it is one of the common malignant tumors in white people, which is more than the sum of all other malignant tumors. The incidence of skin cancer in southern Australia is at least 65 / 100000. Among Caucasians in the United States, the incidence of skin cancer is as high as 165 / 100000, which is 100 times as high as that in China. Basal cell carcinoma is the most common form of skin cancer, accounting for more than 60%. The early manifestations of various skin cancers are mostly erythematous lesions, accompanied by scaly desquamation or scab formation. It is not only difficult to distinguish their histological types by naked eye observation, but also easy to be confused with benign skin diseases such as psoriasis and eczema, which often need to be diagnosed by pathological examination. No matter operation, radiotherapy or other treatment, it has a good effect on skin cancer, and the cure rate can be more than 90%.
In the early stage of skin cancer, erythema or papule like lesions slightly higher than the skin surface are often accompanied by scale desquamation or scab formation, and the symptoms are similar to those of psoriasis, eczema, inflammation and other benign skin diseases. The further development of the focus will show some characteristic signs, such as a shiny, translucent papule like small nodule, with blood oozing on the surface and capillary dilation. Or scar like surface smooth fibroid spots, no obvious capillary expansion, ulcer and uplift. Or there are black, fused dots in the focus.
Through the introduction of our professional knowledge, I believe that our friends have a certain understanding of the early symptoms of skin cancer, so we must pay attention to whether we have the symptoms of skin disease in our life in the future. Once we find that our skin has abnormal performance, we must go to the local hospital for treatment, follow the professional guidance of doctors, and let our skin disease recover as soon as possible.
