The patient named Vu Thi Tu was admitted to the Hospital of Vinh Loc district, Thanh Hoa province with severe pain in her chest and breathing difficulties. The woman was transferred to the provincial hospital, where doctors found a big tumor on her chest and performed urgent surgery to save her life.

Dr. Thiet said: "The patient had a huge tumor and it was more dangerous as it was right in the chest. If we did not conduct an urgent operation, she might have died. After removing the tumor, we were really surprised that the tumor contained many different materials. This is the first time we have ever seen such a strange tumor".

The doctor said that the patient recovered very well and would leave the hospital in a few days.
