Cancer of tissues. What does tissue cancer look like?
Tissue cancer is a process of malignant growth of cancer cells that form a tumor. For cancerous growth, atypical growth, infiltration of pathological tissues into neighboring organs and the formation of secondary oncology foci in the form of metastases are characteristic. Specific manifestations of the disease are individual for each pathology localization. Diagnosis of cancer is carried out through visual examination, radiography, computer and magnetic resonance imaging, biopsy. Soft tissue oncology is to be treated in the following ways: surgical excision of the tumor, radiation therapy and chemotherapy.
Tissue Cancer: classification
- Bone cancer:
Malignant neoplasms of bones arise in two main forms: primary and secondary. The vast majority of bone pathology occurs as a metastatic lesion. This disease is considered quite rare.
According to the histological structure of the tumor, the bones are distinguished:
- Osteosarcoma is a malignant lesion of bone tissue with a progressive growth of osteoid tissue.
- Chondrosarcoma is a cancerous disease of cartilage tissues.
- Ewing's sarcoma is an oncological pathology of the bone andsoft tissue cancer.
The main symptom of bone cancer is a progressive pain syndrome. Deep and aching pain with cancer predominantly occurs at night and does not depend on the physical activity of the patient. In the process of development of malignant neoplasm in the field of pathology edema of hard and soft tissues is observed. In some patients, frequent pathological fractures are noted because of the increased brittleness of bone tissue.
To determine the type of tumor, doctors use a radiographic examination of the bones and a histological analysis of a small area of cancer tissue.
The main therapeutic method is a surgical operation to excise a cancerous tumor. Additional means of combating bone cancer are chemotherapy and radiation exposure.
- Cancer of muscle tissue:
Cancer of the muscle tissue develops from the striated muscle (rhabdomyoma) and smooth muscle (leiomyoma). The course of the disease is accompanied by the formation of muscle tightening, hyperemia (local redness of the skin). Cancer of the muscle tissue at later stages is characterized by the involvement of bone tissue in the pathology. Tumor growth, as a rule, is accompanied by intense pain sensations, which are growing and local in nature.
The diagnosis is made on the basis of examination, ultrasound, computer scan and biopsy (cytological examination).
Therapy of muscle tumors consists in the rapid removal of pathology and subsequent exposure to operated area with highly active X-ray radiation to prevent possible relapses. The rehabilitation period includes a reconstruction operation to restore the function of the organ.
- Adipose tissue cancer:
Liposarcoma in section
Cancer of adipose tissue is represented by liposarcomas, for which a slow development of the tumor is typical, and the tumor can reach huge sizes. In the initial period, the disease manifests itself by the formation of a nodular lesion in the structure of muscle tissue. Liposarcomas metastasize at the first stage of their growth. Secondary foci of cancer are mainly localized in the lung tissue. In the future, the skin layers and bone tissues are involved in the oncological process.
Diagnosis and treatment:
These cancers are diagnosed by X-ray and echography. The final diagnosis is possible after radical excision of the tumor. The removed tissues are sent to the histological laboratory, where the cytological analysis is performed. The prognosis of the disease is mainly favorable, provided early detection of pathology. Liposarcomas very often form relapses, which is associated with multiple metastasis.
- Connective tissue cancer:
The connective tissue in the human body is found in almost every organ. A typical representative of this pathology is fibrosarcoma of the trachea.
Cancer of the respiratory system is accompanied by a violation of the respiratory function, attacks of dry cough, blood masses in sputum and pain syndrome. Malignant neoplasm of the respiratory system can be fully cured only at the initial stage. Diagnosis of tumors of connective tissue is to conduct a subjective study (collection of anamnesis of the disease, clarification of patient complaints) and objective examination (roentgenology, computer and magnetic resonance imaging). To treat this lesion, a surgical technique is used to excise cancerous tissues with the maximum possible preservation of nearby healthy tissues.
Common symptoms of tissue cancer
- Unreasonable and persistent increase in body temperature to 37.0-37.5 degrees.
- Frequently repeated attacks of pain that are not removed by traditional analeptics.
- General malaise, fatigue and loss of efficiency.
- Decreased appetite and body weight.
