What are the early symptoms of bone tumors? These symptoms are very obvious

What are the early symptoms of bone cancer besides knee pain? If a disease like bone tumor occurs in life, we need to pay attention to early detection and early treatment, so that we can recover earlier and help patients reduce harm. In order to effectively help patients with bone tumor diseases, then please let the editor tell you what are the symptoms related to bone tumor diseases?

Bone cancer is a malignant tumor that arises from the cells that make up the bones of the body. This is also called primary bone cancer. Primary bone tumors are tumors that arise in the bone tissue itself, and they may be benign, or malignant. Malignancy (bone cancer) Benign tumors (noncancerous changes) in the bone are more common than bone cancer.

When cancer is found in the bones, it either started in the bones (as in primary bone cancer) or it spread to the bones after starting somewhere else (a metastatic or secondary cancer that spread to the bones). In fact, when cancer is found in the bones, it is usually a metastasis, which has started in another organ or part of the body and then spread to the bones. This cancer that has spread to the bones is named after the place where the primary cancer started (for example, prostate cancer has spread to the bones). Breast, prostate, and lung cancer are among the types of cancer that often spread to the bones in the late stages. Less commonly, cancer can start as a primary cancer in the bones, which is true bone cancer. Primary and metastatic secondary bone cancers are treated differently and have different prognoses.

There are also some cancers that may start in the bones, although they are not considered true bone cancers. Lymphoma is a cancer of the cells responsible for the body's immune response. Lymphoma usually starts in the lymph nodes but sometimes starts in the bone marrow. Multiple myeloma is another cancer of immune cells that usually starts in the bone marrow. These tumors are not considered primary bone cancers because they do not arise in true bone cells.

What are the risk factors for bone cancer?

About 2,300 cases of bone cancer are diagnosed in the United States each year. Primary bone cancer is uncommon, accounting for far less than 1% of all cancers. Bone cancer is more common in children and young adults than in older adults. Cancer found in the bones of older people usually started in another part of the body and spread to the bones.

Risk factors for bone cancer include:

Previous treatment Radiation therapy

Previous chemotherapy with alkylating agents

Gene mutations in the retinoblastoma (RB) gene or other genes

Related disorders, such as hereditary retinoblastoma, Paget's disease of bone, Li-Fremini syndrome, Rothmund-Thomson syndrome, tuberous sclerosis, and Diamond Black Fan anemia

(i) Lumps Early tumors are located in the bone. As the tumor grows, the bone expands and swells more and more obviously. After the tumor breaks through the bone, a soft tissue mass is formed. The lump often appears at the same time as pain, and sometimes the lump is the first symptom. The tumor originates from the bone, so it cannot move. Benign bone tumors grow slowly, are small in size, and the surface and surrounding skin are normal. Malignant bone tumors grow rapidly, the surface skin becomes red and hot, and the subcutaneous veins are filled. Attention should be paid to the location, size, local temperature, texture, boundaries, tenderness, surface properties, mobility and growth rate of the lump.

(ii) Loss of function: Pain or swelling may affect the movement of the affected limb. For example, a tumor at the upper end of the humerus may affect the movement of the shoulder joint. A spinal tumor may limit the movement of the spine and cause it to become stiff or combined with scoliosis.

(III) Deformity: Due to the growth of the tumor, the bone expands and deforms, and its firmness is destroyed. When the weight continues to be loaded, it gradually bends and deforms, such as hip varus, knee valgus, etc. Severe multiple osteochondromas can make children in the growth and development period short and deformed.

(IV) Pain is a major symptom of bone tumors, but the degree varies. Some people only have mild soreness or discomfort; some people only recall some mild pain in the past after the tumor is discovered; some people mistake it for rheumatic pain, which has little to do with treatment and hurts even when resting; some people have severe pain. It is a continuous dull pain or stabbing pain, and analgesics are required. The pain of benign tumors is mild and develops slowly. The pain of malignant tumors is severe and progressive, affecting diet and sleep, and cannot be relieved after rest. The pain worsens at night due to reduced external stimulation, especially the pain of malignant bone tumors at night. The pain is more obvious when it is still, which is the main difference from the pain caused by trauma and inflammatory diseases.

(V) Compression of nerves: Craniofacial tumors compress cranial nerves; tumors near the first rib compress brachial plexus nerves; spinal tumors can cause limb paralysis. The distal end of the affected limb will feel numb due to compression of nerves and blood vessels.

(vi) Fever, weight loss, fatigue, and decreased mobility sometimes occur in advanced bone tumors. Benign bone tumors are usually painless. See a doctor if the following occur.

(VII) Pathological fractures: The growth of tumors within the bone can cause fractures even with slight external force or normal daily activities. The presence of bone tumors is often not discovered until a fracture occurs.

(VIII) Age distribution: The age distribution of bone tumors has certain rules. There are two age peaks in the death of malignant tumors in the population. One is 15 to 20 years old, and the other is 30 to 75 years old. The first peak is mostly primary malignant tumors. For example, malignant bone tumors in 6-month-old infants are almost all neuroblastomas. Ewing's tumor (Ewing'ssarcoma) mostly occurs in children, osteosarcoma mostly occurs in adolescents, lymphoma and other small round cell tumors, giant cell tumors of bone, etc. mostly occur in 20 to 40 years old, and multiple myeloma and metastatic tumors are mostly patients over 50 years old.

(IX) Location characteristics Some bone tumors have relatively specific locations where they are most likely to occur.

Generally speaking, benign bone tumors grow slowly, with mild or no pain. Except for those in the superficial position, they are not easy to detect in the early stage. They are only discovered when the tumor grows or compresses the surrounding tissues, the pain worsens, or pathological fractures occur. Malignant tumors grow infiltratively and develop rapidly. After the bone cortex is destroyed, they can spread to the surrounding soft tissues. The affected area often has spindle-shaped swelling, unclear tumor boundaries, hard texture, local blood vessels dilation, increased skin temperature, and pain in the early stage that progressively worsens. Anemia and cachexia appear in the later stage, and multiple metastatic lesions may occur, among which lung metastasis is the most common.

By carefully reading the article, we already know what symptoms bone tumors will have. Only by understanding these symptoms of bone tumors can we detect the disease in time and take treatment measures in time to avoid missing the best time for treatment and causing too much health harm to patients with bone tumors.
