Microwave Ablation Technique
Microwave ablation is also a type of minimally invasive interventional treatment.
It utilizes high-frequency electromagnetic waves, known as "microwaves," as a "weapon" to destroy tumors.
It is akin to placing the tumor in a "mini microwave oven" for roasting.
Under the guidance of imaging equipment such as ultrasound, CT, and MRI,
the microwave ablation needle is inserted into the tumor mass.
The microwave ablation machine outputs microwaves,
causing the polar molecules within the tumor tissue
to move rapidly and generate heat under the influence of the microwave field.
When the temperature rises above 60°C,
the proteins in the tumor cells denature and coagulate,
leading to irreversible necrosis.
Meanwhile, it stimulates the body's immune system,
enhancing the body's immune function,
helping to suppress the spread of tumor cells.
It is mainly used for solid tumors such as liver tumors, lung tumors, thyroid nodules, breast tumors,
bone tumors, uterine fibroids, pancreatic cancer, and kidney cancer.
It is suitable for patients with primary tumors who cannot undergo surgery due to factors such as age, physical condition, other diseases, or the location of the tumor.
Microwave ablation has high thermal efficiency and short operation times,
with controllable coagulation areas.
It selectively inactivates the tumor while causing minimal damage to surrounding healthy tissues.
The treatment uses only one needle (with a diameter of no more than 2mm),
which, under the guidance of imaging, is precisely inserted into the tumor.
It leaves no scars, has no toxic side effects, and does not involve radiotherapy or chemotherapy.
It is highly safe with a low recurrence rate.
The treatment can achieve tumor reduction, palliative care,
relieve pain, prolong life,
and improve the quality of life.
Microwave ablation is a minimally invasive treatment technique
that utilizes the thermal effect of microwaves.
Under the guidance of ultrasound, CT, and other imaging equipment,
a specially designed microwave needle is percutaneously inserted accurately into the tumor site.
The microwaves released by the needle create a microwave magnetic field,
causing the surrounding molecules to rotate and move at high speeds, generating frictional heat.
When the temperature reaches a certain level (typically above 60°C),
the proteins in the tumor cells denature and coagulate,
leading to irreversible necrosis of the tumor cells,
thus achieving the goal of treating the tumor.
Microwave ablation directly uses microwaves for treatment.
A microwave generator directs high-frequency electromagnetic waves (microwaves) to the tumor tissue in the body.
Under the influence of the microwaves, a magnetic field is created,
causing the charged molecules in the tumor cells to vibrate at high speeds.
