Question 1: How do women determine whether it is breast cancer? What are the symptoms of breast cancer? This is a question that many women want to know. Early-stage breast cancer is easily overlooked, and many people do not discover breast cancer until the late stage. Experts say that when you have the following symptoms, you should go to the hospital for diagnosis in time. 1. Breast lump: Breast lump is one of the common symptoms of breast cancer. In the early stage, the breast lump is limited to the breast parenchyma and can still be pushed. However, once it invades the fascia or skin, the lump cannot be pushed, and the disease is also in a relatively advanced stage. In addition, for patients with early-stage breast cancer, the breast tumors are often small or very hidden, making it difficult to detect. When the disease reaches the middle and late stages of breast cancer, armpit metastasis has already occurred. 2. *** discharge: *** discharge in patients with mid-to-late stage breast cancer is more serious. At this time, smear cytology can be performed on people with *** discharge to confirm the diagnosis. 3. Axillary lymph node enlargement: Patients with mid-to-late stage breast cancer often experience axillary lymph node enlargement, invasion of lymphatic vessels, and distant spread and metastasis. The most common site of lymphatic metastasis for distant spread of breast cancer is ipsilateral axillary lymph node metastasis. 4. Breast pain: Most patients with early-stage breast cancer have no obvious pain. However, in patients with mid- and late-stage breast cancer, breast pain is more obvious, with multiple stabbing pains, dull pain, etc. ? The above four major symptoms are the typical symptoms of breast cancer, which are of great clinical significance. Hope it helps patients.

Question 2: How to judge breast cancer. The main early detection methods of breast cancer are as follows:

① Ultrasound examination: micro calcifications in the breast mass, edge spiculation sign, aspect ratio greater than 1 , the greatest possibility of cancer. Observing the peak flow velocity of cancer blood flow, the average density of color pixels, and the average density of blood vessels through semi-quantitative methods and color capture technology are of great help in identifying benign and malignant tumors. Penetrating vessels and MVD have higher sensitivity in diagnosing breast cancer.

②MRI examination: The detection rate of breast cancer using paramagnetic contrast agent enhancement followed by MIP reconstruction is 100%. MRS strongly indicates that the choline level in breast cancer tissue is increased and the water/fat ratio is significantly greater than that of normal tissue, which is an important criterion for the diagnosis of breast cancer.

③CT examination: Thin-section scanning can detect cancer lesions with a diameter of 0.2cm. The related parameters of breast cancer increase are closely related to MVD. Better display of metastatic lymph nodes.

④X-ray examination: The most advantageous for detecting calcifications of breast cancer. X-ray digital photography is helpful for CAD. MWA and CMRP technologies can improve the reliability of breast cancer diagnosis.

⑤ Infrared thermography: Use a digital quantitative system to quantitatively analyze the temperature of breast cancer hot spots, calibrate the temperature difference between the center of the lesion and the surrounding tissue, and determine whether the mass is benign or malignant.

⑥ Minimally invasive imaging: Ultrasound-guided biopsy is carried out for tiny lesions lacking imaging characteristics, and 3D CE PDU improves the quality of biopsy guided by ultrasound imaging and CT.

Question 3: How to distinguish early stage breast cancer from late stage breast cancer? The early symptoms of breast cancer are generally judged from several aspects:

1. Mass:

** * Masses vary in size, mostly single, occasionally multiple. The masses are mostly round or oval, with unclear borders. They are generally indurated and have poor mobility.

2. Pain:

Early manifestations of breast cancer? There will be pain in the early stage, mostly manifested as tingling, swelling or dull pain, which are early clinical manifestations. Breast cancer is difficult to detect because painful symptoms are very rare. But as long as you observe your life carefully, it is still easy to find. You must be vigilant to prevent the occurrence of breast cancer.

3. *** Skin changes:

*** Skin changes will occur in the early stages of breast cancer. Dimple signs can appear early in breast cancer, on the affected side. It is more obvious when moving the arms up and down. This is also an early symptom of breast cancer.

Let’s introduce the symptoms of late-stage breast cancer

1. Breast cancer hardness: Breast cancer tumors are hard in texture, but cell-rich medullary cancers can be slightly softer, and some may be slightly softer. Can be cystic, such as cystic cancer. Around a few tumors, there is more fat tissue wrapped around them and they feel flexible when palpated.

2. Mass activity: When the mass is small, the activity is greater, but this activity is that the mass moves together with its surrounding tissues, which is different from the activity of fibroadenoma.

3. Axillary lymph node enlargement: rarely seen as the first symptom of breast cancer (unless occult breast cancer). Most of them indicate the progression of breast cancer, and it is necessary to rule out metastasis of other malignant tumors in the upper limbs, shoulders, back, and chest. Pathological examination can help confirm the diagnosis.

4. The location of breast cancer: The breast is centered on the *** and a cross is made. The breast can be divided into upper inner, upper outer, lower inner, lower outer and central (areola) 5 districts. Breast cancer is more common on the outside, followed by the inside. Inside and outside are less common.

5. Number of symptoms of breast lumps: Breast cancer is more common with a single lump in the unilateral breast. Multiple unilateral lumps and primary bilateral breast cancer are rare in clinical practice. However, as the level of tumor prevention and treatment improves, the survival period of patients continues to extend. After breast cancer surgery on one side, the chance of developing a second primary cancer in the contralateral breast will increase.

Question 4: How to judge breast cancer metastasis? The most common areas for breast cancer metastasis are the lungs, liver, bones, and brain.

It can be checked through chest X-ray, abdominal B-ultrasound, whole-body bone scan, and head CT.

The first two are routine examinations, including preoperative examination and postoperative review. Bone scans and head CT are usually chosen when symptoms are present.

PET-CT can scan the whole body at once and is highly sensitive to tumor diseases, but it is more expensive and can be used by qualified patients.

Question 5: How to judge whether you have breast cancer? Go to the hospital to find a doctor and judge based on B-ultrasound and other examination results. Wouldn’t it be delayed if I made a wrong judgment?
