How to diagnose malignant tumors?
Diagnosis of Malignant Tumors 1 Histology – Histology orMicroscopic examination of a tumor mass with the help of a biopsy. This is the most valuable and the most reliable method to diagnose if the tumor is benign or malignant and even for staging the cancer. 2 Cytology – fine needle aspiration cytology ( FNAC) collects samples of a lesion to be examined under a microscope. The procedure is less painful as compared to a biopsy. 3 Histo-chemistry and Cytochemistry – This method is an additional tool to help in understanding the chemical composition of cells by using various staining methods. 4 Electron Microscopy – This ultra-structural microscopy helps to understand the structure of tumor cells and their components for diagnostic purpose. 5 Tumor Markers – Tumor markers are biochemical assays of products secreted by a malignant tumor. Tumor markers support a diagnosis and they also help in prognosis.#N#Example of certain tumor markers:#N#● Alpha-feto protein – hepatocellular carcinoma#N#● Prostate Specific Antigen (PSA) – Prostate Cancer#N#● CA-125 – Ovarian Cancer#N#● CA-15-3 – Breast Cancer 6 Flow Cytometry – This is a computerized technique to understand characteristics of tumor cells in detail and to store data for subsequent comparison.

Overview
A tumor is a mass or group of abnormal cells that form in the body. If you have a tumor, it isn’t necessarily cancer. Many tumors are benign (not cancerous).
Symptoms and Causes
Your body is constantly making new cells to replace old or damaged ones that die off. Sometimes, the cells don’t die off as expected. Or, new cells grow and multiply faster than they should. The cells start to pile up, forming a tumor.
Diagnosis and Tests
Your healthcare provider performs a biopsy to determine whether a tumor is cancer. A biopsy involves removing cell samples from a tumor. A pathologist (a medical doctor who studies diseases) examines the samples in a lab to make a diagnosis.
Management and Treatment
Treatments for a tumor depend on many factors, including the tumor type (malignant or benign) and location.
Prevention
Most tumors occur for no known reason. Still, these steps may lower your risk of developing a tumor:
Introduction
Two or more primary malignant tumors occurring simultaneously or successively anywhere in the body are diagnosed as multiple primary malignant tumors (MPMT). MPMT is rare.
Case Presentation
A 30-year-old female presented to our hospital on December 4, 2017 due to a 4-month-old mass on her left breast. She did not complain of pain, dizziness, headache, or any other discomfort, and did not report any relevant family history. Physical examination revealed a palpable mass, 6×5 cm in size, at 3 o’clock on the left breast.
Discussion
The incidence of MPMT in China (0.4–2.4%) is significantly lower than that reported by other countries (0.73–11.7%), 1 and may be related to a lack of understanding of the disease or its misdiagnosis as metastasis or recurrence. Clinically, MPMT is often confused with recurrence or metastasis of malignant tumors.
Ethics Statement
Written informed consent was obtained from the included patient, and the patient agreed to publish the details of her case and any accompanying pathological images. This study and the publication of the case’s details were approved by the ethics committee of the First Hospital of Lanzhou University.
