The cancer monument was erected in honor of the blacksmith, the hero of the legend of Insk. The community of Norenberg, Germany, came up with the initiative to erect a monument by the lake. Former inhabitants of Insko are its co-founders. The cancer monument was made of metal by the metalwork workshop in Stargard. In 2005, it was placed right next to the lake. It is supposed to remind the inhabitants of the legend of Inska. According to her, a long time ago, a crayfish lived in the waters of Lake Insko. He was big and very strong. He even split stones and cut down trees with his great scissors. When he came out of the lake, he made havoc around. The people were very afraid of him. They fled to their homes, but they were not a sufficient hiding place. Cancer with its pincers even destroyed the walls around the town. One Sunday, when the cancer was on the hunt again, people hid in the church. They thought he would not dare enter this sacred place. But they miscalculated. The beast then destroyed part of the church, and with one wave of the pliers tore off the roof of the building. The inhabitants grew more and more fed up with the cruel cancer. They were trying to get him out of town. They made a great metal net in which they tried to catch him. But in vain, the crayfish chopped the net into tiny pieces with its pincers. And as an act of revenge, he plundered all the boats that stood by the lake. It was a blow to the inhabitants, because they made a living from fishing. Cancer did not stop its attacks on the inhabitants of Insk. They lost faith that they could defeat him. Hope dawned on them when the young blacksmith devised a cunning plan for cancer. He forged a chain of hardened steel for it. He commissioned the inhabitants to build a large boat that could accommodate ten daredevils. A boat with a chain was lowered into the water at night. The blacksmith with the strongest men in the town swam to the place where the crayfish usually slept. One end of the chain was wrapped around his tail. The second was attached to the bottom of the lake. Cancer tried to break free, but in vain. He has been permanently trapped in the lake. People breathed a sigh of relief, and the blacksmith became their hero. The cancer is said to sleep at the bottom of the lake to this day.
