What are the early symptoms of cancer?

First: mass: formed by malignant proliferation of cancer cells, which can be touched by hand on the body surface or deep. Cancer of the thyroid gland, parotid gland or breast can be touched in the shallower part of the skin. Metastasis of tumor to lymph nodes can lead to lymph node enlargement. Some superficial lymph nodes, such as cervical lymph nodes and axillary lymph nodes, are easy to touch.

Second: pain: pain often indicates that cancer has entered the middle and advanced stage. At first, it was dull or dull pain, and obvious at night. Later, it became more and more intolerable, day and night. General painkillers don't work. Pain is usually caused by cancer cells invading nerves.

In addition, gastric, colon cancer can also form ulcers, generally only through gastroscope, colonoscopy can be observed.
