Squamous cell carcinoma and adenocarcinoma are the most typical cancer diseases. In recent years, the incidence of squamous cell carcinoma is getting higher and higher, which causes a lot of troubles to our daily life. Do you know the difference between squamous cell carcinoma and adenocarcinoma? Let's get to know.

What's the difference between squamous cell carcinoma and adenocarcinoma

1. Development progress

The development of adenocarcinoma is fast and the course of disease is very short. The tumor will continue to infiltrate into the depth, often with the normal cell boundary unclear, the tumor lack of mobility, relatively fixed location. In the late stage of adenocarcinoma, it will invade the skin, muscles, nervous system, bone cells, etc. the surface of the tumor is prone to ulceration and severe pain.

2. Growth site

There is a great difference between the location of squamous cell carcinoma and adenocarcinoma. Squamous cell carcinoma usually grows in squamous epithelial cells. The multiple sites of the tumor are covered by the inherent squamous epithelium of human body, such as skin, mouth, cervix, esophagus, vagina, penis, etc. And adenocarcinoma is the tumor that disease sends in glandular epithelial cell commonly, basically can send in gastric ministry, bowel, breast, liver, bronchus, thyroid to wait.

3. Clinical symptoms

The clinical symptoms of squamous cell carcinoma and adenocarcinoma are quite different. The differentiation degree of squamous cell carcinoma varies according to the type of tumor. The disease course is generally longer and the growth rate is slower. Squamous cell carcinoma is easy to metastasize in the late stage, at the same time, it usually first metastasizes through the lymphatic system, and then hematogenous metastasis.

4. pathology

(1) Squamous cell carcinoma. In clinic, the main manifestation of squamous cell carcinoma is cauliflower. If the cancer tissue has necrosis, it can fall off, form ulcer, and smell. If cancer cells go deep, they can form aggressive growth. Squamous cell carcinoma is prone to distant metastasis, forming a secondary tumor. In the early stage of cancer, there are red induration and other skin lesions, which can slowly develop into verrucous lesions, infiltration, etc., often accompanied by odor, ulcer, purulent secretion. According to the degree of differentiation, squamous cell carcinoma can be divided into three types: high differentiation, medium differentiation and low differentiation.

(2) Adenocarcinoma. Adenocarcinoma cells have different shapes, mainly round, oval and so on. Most of the cells are not enveloped and complete. The cytoplasm of the cancer is relatively hard and the section is gray white. In the microscopic examination, it can be found that the cancer cells have obvious heteromorphism, which can be solid masses or small cords. If it is adenoid structure, it indicates that the differentiation of cancer cells is relatively high and the malignant degree is relatively low. Adenocarcinoma is highly invasive and destructive. It is easy to invade blood vessels and lymphatic vessels and often has lymphatic metastasis.

The above is about the difference between squamous cell carcinoma and adenocarcinoma. I hope it can help you. There is a big difference between adenocarcinoma and squamous cell carcinoma, so we should not confuse the two diseases. Otherwise, it is easy to have treatment errors, delay the best time for treatment, and make life seriously threatened
