Oncologist Rasul Akhmaev has outlined specific late-stage cancer symptoms that require immediate medical attention during an interview with Russian news outlet Lenta.ru.
Dr Akhmaev, a chemotherapist at the SM-Clinic medical network, explained that oncological diseases generally progress through four stages. He noted that stages one and two are classified as early phases, while stages three and four represent late-stage progression.
According to Dr Akhmaev, most types of cancer remain completely asymptomatic during their early phases as tumors grow unnoticed inside the body. Obvious physical warning signs only begin to manifest during the third and fourth stages, varying depending on the specific location and nature of the malignancy.
SM-Clinic is one of Russia's largest private healthcare networks, operating multi-specialty medical centers and diagnostic facilities. In clinical oncology, disease staging provides a standardized framework for doctors to describe the extent of cancer growth, with lower numbers indicating localized tumors and higher numbers reflecting more advanced spread.
Symptoms across specific cancer types
Dr Akhmaev highlighted that specific warning signs depend heavily on the organ system affected by the disease. For breast cancer, patients typically observe visible or tangible changes in the breast tissue, as well as the appearance of unexpected lumps under the armpit.
In cases of stomach cancer, warning signs include nausea, vomiting, and black stool. Prostate cancer may present with blood in the urine, painful urination, or persistent pain radiating into the hips or lower back.
For malignancies affecting the blood-forming system, primary indicators include a persistent high temperature and profuse night sweats. Hematological cancers affect blood cell production and bone marrow, often disrupting the normal immune system.
In addition to site-specific signs, general symptoms frequently appear across late-stage cancers. Dr Akhmaev noted that overall weakness and unexplained rapid fatigue are widespread in late stages, because the body expends nearly all its energy attempting to fight the advancing disease.
Diagnosis and multidisciplinary treatment boards
Dr Akhmaev emphasized that symptoms alone cannot be used to make a definitive diagnosis, serving instead as an urgent prompt to seek professional medical evaluation. Initial diagnostic procedures vary according to the specific symptoms presented by the patient.
Medical diagnostics for suspected cancer typically involve diagnostic imaging, laboratory blood testing, and tissue biopsies to confirm the presence of malignant cells. Once diagnostic testing produces conclusive results, a formal diagnosis is established.
A multidisciplinary oncology board, known in Russia as an oncoconcilium, then meets to determine the appropriate treatment strategy for the individual patient.
The medical board consists of multiple specialists, including an oncologist, a surgeon, a radiotherapist, and a chemotherapist. Dr Akhmaev stated that a board decision is rendered for every cancer patient in Russia, noting that treatment is never prescribed through any other method.
Multidisciplinary tumor boards are standard practice in modern oncology worldwide. Surgical oncologists focus on tumor removal, chemotherapists manage systemic drug treatments, and radiotherapists administer targeted radiation therapy to treat malignant tissue.
Dietary claims and lifestyle factors
The discussion follows previous advice from oncologist Anastasia Fatyanova, who stated that no single food product can halt the spread of cancer cells or prevent them from appearing in the body.
Dr Fatyanova noted that protective benefits come solely from broader lifestyle habits. She emphasized that while a well-balanced diet plays a significant role in overall health, individual food items do not possess curative or preventative properties against cancer.
